The reasons that led many Latinx individuals in South Texas to participate in the primaries are numerous and varied, but not entirely surprising, considering recent polls, according to analysts and Democratic candidates themselves. In five rural counties in South Texas with a Latinx-majority population, the number of voters who participated in Tuesday's Democratic primaries exceeded the number who supported Kamala Harris in the 2024 presidential election. 'This is what we're seeing, and it could be an indicator of what's to come, not just in South Texas, but across the country,' said Pulido. Many Democratic candidates, including Pulido, understand that the Latinx vote—like the unexpected support shown for Trump in 2024—has always been more volatile than many assumed. Now, it appears that a combination of ongoing inflation, tariffs, and immigration policy seen as overly strict has once again pushed this bloc of voters toward the Democratic Party. This marks a significant shift after the erosion of Latinx support for the Democratic party in South Texas, a region historically dominated by Latinx residents and considered one of the party's most steadfast strongholds for over a century. The Republican strategy for redistricting, by contrast, was based on the exact opposite idea: that the realignment of Latinx voters was structural and permanent. For example, the 35th District, currently represented by a Democrat in Washington, was redrawn to include Latinx-majority areas of San Antonio and Austin, in the hope that it would flip to Republican hands by 2026. This trend has implications that extend far beyond these primaries. Republicans redrew electoral maps along partisan lines last year to gain five additional seats in the House of Representatives, confident that their gains among Latinx voters would continue. Indeed, many of the districts they hoped to win or secure are in the southern part of the state with a Latinx majority, but the mobilization that occurred on Tuesday threatens to upend these calculations. The situation in Zapata County, located on the border south of Laredo in the Rio Grande Valley (as the entire region is known), perfectly reflects this dynamic. There, 94% of the population is Latinx. Over the past decade, Trump's support in the county grew from 33% in 2016 to 61% in 2024. The shift to the right was so stark it formed a national warning about the fragility of what was assumed to be an entrenched relationship between the Democratic Party and the Latinx community. This momentum and renewed political mobilization were particularly crucial factors in James Talarico's victory in the Democratic primary for the Senate against Jasmine Crockett. Talarico won by a margin of about 22 points in Latinx-majority counties, compared to a margin of just three points in the rest of the state. 'Our community is a testament to the American dream—people who work hard and believe in opportunity,' he said. 'When families feel that dream is not being realized for them, they raise their voices.' Nevertheless, the turnout and primary election results this week suggest the tide may be turning again, as Latinx voters express deep disappointment with the policies and tactics of the Trump administration. Bobby Pulido, a winner in a Democratic primary in one of the southern counties, summarized the matter as follows: 'The Rio Grande Valley proved its existence, and that says a lot.' Pulido added: 'For years, people assumed Latinx voters wouldn't turn out for primaries, but South Texas proved that's not the case.' Yet, on Tuesday, Zapata was one of five counties—along with Kennedy, James Hogg, Reeves, and Dimmitt—where Democratic primary turnout exceeded the total participation in the November 2024 election. Still, the Democratic primary in that district drew 7,500 voters, more than the Republican primary, despite Trump winning the county by 10 points in 2024.
