The White House dispatched Vice President JD Vance to South Texas on Wednesday in an effort to hold together President Donald Trump's disintegrating coalition, but analysts and New York Times reporters — per the paper's live midterm coverage — say the Republican tent has largely collapsed. The trip lands at a decisive moment in a midterm cycle in which seats in both the House and Senate are in play, giving Republican-held territory once considered secure outsized importance in the battle for Congress.

Vance is stumping in a district that Trump and the Republican Texas legislature gerrymandered to be more favorable to the GOP, in a border region "where eroding support for President Trump has raised Democratic hopes of flipped seats in both the House and the Senate," according to the Post. The dynamic makes the district a test case for whether mapmaking designed to entrench a Republican advantage still holds against shifting voter sentiment on the ground.

At the heart of the party's anxiety is Hispanic support. Vance rallied for the Republican challenger to Representative Vicente Gonzalez in a race that remains tightly contested, despite Trump and Texas Republicans having redrawn the district around what they believed was a loyal Hispanic contingent that once backed the president. Because Democratic hopes of flipped seats run through border districts like this one, the outcome carries implications for the national balance of power in Congress.

"Hispanic voters in South Texas have soured on Mr. Trump, growing increasingly angry over the handling of the economy and immigration enforcement," reported Times writer Patricia Mazzei. "At a White House event for Hispanic Heritage Month, Mr. Trump sought to defend his border policies, but his remarks focused only episodically on Hispanic voters."

Times reporter and noted author Maggie Haberman pointed out that Trump's support among Hispanic voters "has suffered in the last two years, in part over his administration's immigration crackdown and efforts at mass deportations."

Trump only sporadically defended his immigration policies during the Hispanic Heritage Month event, where he "made fleeting mention of the criticism he has faced from members of his own party, including those running for office," reported Erica Green.

"No matter what you do,'s always tough," Trump said. "But we have, we've been very strong."

Meanwhile, the Times reports that the campaign of Republican Senate nominee Ken Paxton announced it would spend $20 million on a new round of advertising in Texas, starting Friday in the state's biggest markets — Houston, Dallas, Austin and San Antonio — before expanding to all corners of the state. The Friday launch places the buy squarely in the closing stretch of the campaign, when late-deciding voters are typically still making up their minds.

Times reporter J. David Goodman reports that the new spending follows tens of millions already spent by groups supporting Paxton in recent weeks, as Paxton falls behind in his race against his more popular Democratic opponent. The escalating price tag underscores how fiercely contested the Texas Senate race has become.

Vance attempted to tie Paxton's opponent to the national Democratic Party, framing the election as a choice between Paxton and James Talarico "as an avatar for the broader Democratic Party," reports the Times.

Still, Paxton's onerous unpopularity appears to be outshining state voters' generations-long suspicion of Democrats. And recent gaffes from Paxton — already a flawed candidate with marriage infidelity issues and corruption complaints — have done nothing to help him. From here, the markers to watch are Friday's advertising launch and whether the erosion the Times is documenting across South Texas holds through Election Day.
