SMU researcher says proposed Tarrant County redistricting 'diminishes' voting power
The Brief
Tarrant County commissioners are set to vote on new district maps within days, a process led by Republican County Judge Tim O'Hare.
Critics say the proposed maps violate racial protections in the Voting Rights Act by concentrating non-White voters into one district, diluting their voting power.
An SMU researcher's analysis appears to suggest the new maps may be biased against non-White voters.
TARRANT COUNTY, Texas - The Republican-led Tarrant County Commissioners Court is days away from voting to redraw district lines.
Critics say the proposed maps violate racial protections in the Voting Rights Act. Now, an SMU researcher is applying her own mathematical review to the maps.
The Latest
SMU mathematics professor and researcher Dr. Andrea Barreiro has dissected and analyzed the newly proposed maps for Tarrant County districts, the work of a county-hired consulting firm and the public legal interest foundation.
The researcher uses mathematics and technology to analyze the redistricting models. She says she was drawn to Tarrant County's current process as attention surrounding the topic began to grow. Barreiro looks for signatures of partisan and racial gerrymandering, she says.
The current process to redraw the county's lines is led by Republican County Judge Tim O'Hare.
At the center of the controversy are District 1, held by Commissioner Roderick Miles, and District 2, a seat now held by Commissioner Alisa Simmons, both Democrats.
What they're saying
"It looks like they made small modifications on this basic template where they swap the purple and the blue to get their desired outcome," Barreiro said.
Barreiro says a randomly unbiased generated map based on the latest census data would have 60 to 65 percent non-White voters in each of those districts.
"The proposed maps do something very different," Barreiro said. "They take a lot of those non-White voters in District 2, and they pack them into District 1, leaving District 2 to be majority White."
Barreiro uses advanced software, applying a method known as Markov Chain Analysis. Her experience using the same technology includes similar analysis her team prepared during the state legislative redistricting cycle.
"We have continued to reach out to Judge O'Hare for his response to allegations of racial gerrymandering by Simmons, Miles, as well as U.S. Congressman Marc Veasey and ten Tarrant County mayors," Barreiro said.
Barreiro stops short of making a legal opinion on whether the proposed maps violate state and federal law. She does say it is clear what the consultant map-maker's mission is.
"If black voters could be a large presence in two districts, but instead you pack all those people by picking your map cleverly, you get all those people into one district, then you diminish the voting power of that population," Barreiro said. "There are interesting methodological and mathematical questions about this whole process that I'm eager to explore, and I'm also just interested in basic fairness."
What's next
Late Thursday afternoon, O'Hare agreed to an interview with FOX 4. The meeting is set for Friday morning.
A vote on Tarrant County's redistricting process is set for Tuesday.
The backstory
The mayors of 10 Tarrant County cities, including Fort Worth, Arlington, Mansfield, and Grand Prairie, have signed a letter expressing their opposition to the proposed map.
The group called the effort ill-timed because it's the middle of the decade and, in their opinion, the census data from 2020 is outdated.
In early April, the commission voted three to two, with commissioners Alisa Simmons and Roderick Miles opposing, to approve a contract with the Public Interest Legal Foundation to provide consultation with re-drawing district lines.

Minnesota Gov. Tim Walz's next move: Energizing Democrats in South Carolina and California
MINNEAPOLIS -- Minnesota Gov. Tim Walz will seek to energize activists at Democratic state conventions in South Carolina and California on Saturday, as the party's 2024 vice presidential nominee works to keep up the high national profile he gained when Kamala Harris selected him as her running mate. Walz, a former schoolteacher who went to Congress and then became his state's governor, will keynote the South Carolina gathering in Columbia, traditionally a showcase for national-level Democrats and White House hopefuls. Another leader who often appears on those lists, Maryland Gov. Wes Moore, spoke Friday night at the party's fundraising dinner. South Carolina held the first Democratic presidential primary of the 2024 campaign, and the party hopes for a repeat as first in line in 2028. But the national party organizations haven't settled their 2028 calendars yet, and party officials in Iowa, New Hampshire and Nevada are also vying to go first. 'From the classroom to the governor's office, Tim Walz leads with compassion and common sense,' the South Carolina party posted on social media earlier this month when it announced his appearance. 'He's proof that you can govern with both heart and backbone, and he's bringing that message to South Carolina.' Walz, who's on a long list of potential 2028 candidates who have been traveling to early-voting states, will also be a featured speaker as California Democrats gather in Anaheim on Saturday. 'We're fired up to welcome Minnesota Governor Tim Walz to the Convention stage in Anaheim,' state chair Rusty Hicks said in a statement. 'He's a former teacher, a veteran, and a trailblazer who's spent his career fighting for working families and standing up for the values we all share — fairness, dignity, and opportunity for all.' Democrats have been debating since Harris lost to President Donald Trump in November over which direction the party should take. That self-examination reflects deep frustrations among Democratic voters that their leaders are failing to put up enough resistance against Trump, who has taken a much more aggressive approach to his second term in the White House. Walz hasn't officially said if he'll seek a third term in 2026, but acknowledges he's thinking about it. He said in a recent interview with KSTP-TV that he would probably wait to decide until July, after he calls a special session of the closely divided Minnesota Legislature to finish work on the state's next budget. Those negotiations have gone slowly despite his frequent meetings with legislative leaders. He's given mixed signals on a 2028 presidential run while keeping up his attacks on Trump. He told The New Yorker Radio Hour for an interview that aired in March that he would 'certainly consider that' if circumstances were right. He told CNN's 'State of the Union' last month that he was 'not thinking about running in 2028.' But he hasn't ruled it out, either, and has signaled possible interest in other ways. Following the Democratic ticket's defeat in November, Walz returned to the road in March when he went to Iowa to launch a series of town halls in competitive congressional districts represented by Republicans, after House Speaker Mike Johnson advised GOP representatives to avoid holding town halls because of protests at them. Walz's gubernatorial campaign organization, which has been actively raising money, has used his travels in 'Support Tim on the Road' fundraising pitches. 'For the past few weeks, I've been showing up where Republicans won't,' he wrote in one recent message. 'I've hosted town halls in Iowa, Nebraska, Wisconsin, Minnesota, and Texas to hear from people the GOP is neglecting.'

Heavy-hitters arrive in South MS as contentious Gulfport mayor's race nears end
Through phone calls, mailers and high-profile endorsements, the candidates vying to become Gulfport's next mayor are making a final push to lure voters this week at the end of what has become an intense and high-stakes campaign. In a rally on Friday headlined by U.S. Sen. Tim Scott of South Carolina, Republican leaders spoke in urgent terms about a race they called tight and too important to lose. 'This will take the extra-mile effort,' Scott said from a private hangar at the Gulfport-Biloxi International Airport. How the city votes, he added, 'is going to be a sign for Mississippi.' Scott, who was once floated as a possible running mate to President Donald Trump, appeared Friday on behalf of Republican mayoral candidate Hugh Keating. He spoke alongside U.S. Sen. Cindy Hyde-Smith, U.S. Rep. Mike Ezell and outgoing Gulfport Mayor Billy Hewes. The rally came during a tense week of the campaign: Mississippi's Republican Attorney General Lynn Fitch announced an investigation on Wednesday into Democratic candidate Sonya Williams Barnes after Republicans accused some locals of giving restaurant vouchers to voters in what the party calls a violation of state law. Democrats, though, are defiant: Barnes called the allegations false this week and said she has 'not engaged in any form of voter fraud.' Supporters who turned out for her in big numbers during the primary are condemning the news as a politically-motivated distraction and say they have faith their grassroots effort will prevail. Barnes did not immediately return a message Friday afternoon. But she has said her team is knocking on doors and calling voters in a campaign that is 'organized, energetic and grounded in the belief that our city deserves new leadership that listens, leads with integrity and acts in the public's best interest.' 'I'm running because I hear the call for change from every corner of our community,' she said in a statement this week on social media. The Republican rally was billed as an effort to get out the vote and swelled to about 200 people. Republicans there said the Democratic energy behind Barnes campaign was a wake-up call that should galvanize voters. The crowd, some wearing red Trump hats, nodded along. Barnes won the April Democratic primary with 3,316 votes. Mayor Billy Hewes, a Republican who is not running again, won the 2021 general election with 2,680 votes. Keating had no Republican opponent in the primary. City officials said they had received more than 1,000 absentee ballots by Thursday evening. There were 177 absentee voters in the 2021 general election, according to the city. Hyde-Smith said she asked Scott to visit Gulfport after she learned Democratic operative Stacey Abrams was supporting Barnes. Abrams grew up in Gulfport, and she and Barnes are the children of United Methodist ministers who were friends. Republicans have said her support is part of national Democratic effort to turn Gulfport blue. Barnes has said she alone is responsible for running her campaign and called similar statements divisive. At the Capitol on Thursday, a group of legislative Democrats gathered to reject the election fraud claims leveled by the state Republican Party. 'This election has been very fair, very balanced. But these are scare tactics of the Republican party that have been used for years,' said Rep. Cheikh Taylor, Chairman of the Mississippi Democratic Party. 'The fact is, she's winning. And she's winning in an area that's uncommon for a lot of Democrats. She's going to make history as the first African American female to become mayor, and I think people are afraid.' The status of the Attorney General's investigation is not clear because the office does not comment on open inquiries. Barnes said she and her attorney met with two investigators from the Attorney General's Office on Thursday. 'I fully cooperated with the investigators and answered every question asked of me,' she said in a statement on social media. 'These accusations are false, and I stand firmly on the truth.' Keating said news of the investigation had not significantly changed Republican voters' absentee turnout. 'We were already energized,' he said. Mississippi Today reporters Michael Goldberg and Geoff Pender and Sun Herald reporter Anita Lee contributed.

HARTFORD, Conn. (WTNH) — The clock is ticking toward the end of the state legislative session. On Friday lawmakers gave an update on the state's next two-year budget during news briefings. Democratic House Speaker Matt Ritter said the budget is being 'drafted.' Gov. Lamont: Budget on the '1-yard line' It's expected to be voted on early next week after much back-and-forth. 'I don't know Monday, maybe Tuesday,' Ritter said. 'On the spending side it looks like we've reconciled all the numbers according to those 25-line items and figured it out.' Meanwhile, House Republican leaders talked about their 'ambitious agenda' Friday, saying they won't back down on Senate Bill 4, which is focused on energy bill costs and the makeup of the Public Utilities Regulatory Authority (PURA). 'I think if it doesn't address the structure of PURA,' Republican Minority Leader Vincent Candelora said. 'To make sure it is operating in a transparent way, with a body of five making decisions, yes I would block that bill.' Lawmakers will reconvene this weekend. The legislative session ends on June 4.
