A spate of recent polls signals that Democrats are gaining traction in both the races for United States Senate and the governor’s mansion in Texas, turning a reliably Republican state into a battleground ahead of the November midterm elections.

On Friday, the nonpartisan research initiative Texas Pulse, helmed in part by the Texas A&M Bush School of Government and Public Service, released its latest public opinion survey into the state’s midterm races.

It found that James Talarico, the Democratic nominee, is now leading the US Senate race by four points, with 47 percent support. His Republican rival, state Attorney General Ken Paxton, trailed at 43 percent.

Those statistics suggested growing momentum for Talarico, who was tied with Paxton in an earlier Texas Pulse poll from June.

Texas Pulse’s findings echo another poll, released on Thursday, that showed Talarico leading Paxton 48 percent to 45 percent. Another 6 percent of respondents said they were undecided.

That poll, conducted by the research firms YouGov and 254 Labs, suggested that Talarico had a significant advantage among undecided and independent voters in the Lone Star State.

An estimated 57 percent of independent voters preferred the Democratic candidate over his Republican competitor, although 20 percent said they remained undecided.

A Fox News poll from late July similarly found that 68 percent of independents are getting behind Talarico, a 37-year-old state representative.

While polls can vary dramatically in the months leading up to an election, the latest survey results are likely to serve as a bellwether for Democratic odds in November’s midterms.

The left-leaning party is hoping to wrest both chambers of Congress from Republican control.

Should Democrats succeed in doing so, their majorities could serve as a bulwark against President Donald Trump’s legislative agenda during the final two years of his presidency.

But analysts believe the Senate may be more difficult to flip than the House of Representatives. While all 435 seats in the House are up for grabs in November, only a third of the Senate is on the ballot.

That makes every Senate race critical to either party maintaining — or retaking — control of the upper chamber.

Cost of living concerns

Texas has long-established bona fides as a Republican stronghold. No Democrat has held statewide office in Texas in more than three decades.

But the open Senate seat in Texas has created an unusually competitive race for Democrats.

Paxton, the Trump-endorsed candidate, defeated the incumbent Senator John Cornyn in the Republican primary in May.

But the longtime state attorney general has generated concerns among Republicans about his ability to appeal to centrist voters.

Paxton’s career in politics has been riddled with corruption scandals. During his tenure as the state’s attorney general, he has faced allegations of abuse of office and misconduct involving a political donor, the latter of which resulted in his impeachment — though he was not removed from office.

He also faced a separate, nearly decade-long securities fraud case that was dismissed last year. His support for the attack on the US Capitol on January 6, 2021, and accusations of adultery have also been sources of criticism.

A Texas Public Opinion Research poll, released last week, found Paxton trailing Talarico by five points, 45 percent to 40 percent.

Notably, that poll suggested that the Democrat leads by 34 percentage points among self-described moderates, with 54 percent support to Paxton’s 20 percent.

Experts like Evan Roth Smith, the lead pollster for Texas Public Opinion Research, credit that upward momentum to a solid campaign pitch.

“Talarico is up because he’s running the race every Democrat in this country should be running. When they go on TV, podcasts and talk to reporters, they should focus on affordability. If we can win on affordability, we can win elections,” Smith told Al Jazeera.

Talarico, a former educator with a seminary background, has largely concentrated his campaign on cost-of-living and economic issues, proposing to raise the federal minimum wage.

He also recently unveiled a plan late last month to end tax breaks for tech companies building data centres.

Paxton’s economic agenda, meanwhile, has focused on tax breaks, including a $25,000 tax deduction for out-of-pocket medical expenses and a $50,000 deduction for first-time homebuyers.

But Texas’s Senate contest is not the only statewide race generating attention for its competitiveness this election cycle.

The gubernatorial race is also getting tighter between Democratic state Representative Gina Hinojosa and Republican incumbent Greg Abbott. That race is neck and neck.

Abbott’s lead has shrunk from six points to a single point, with Abbott at 46 percent and Hinojosa at 45 percent, according to Friday’s Texas Pulse poll.

The Texas Public Opinion Research poll has Abbott leading by three points, with 45 percent support compared with 42 percent for Hinojosa. A wild card, however, remains in the 10 percent of respondents who identify as undecided.
