Super Tuesday primaries 2024: Trump and Biden dominate, Haley drops out

With Texas Republican Sen. Ted Cruz projected to win his primary — he's got 89 percent of the votes counted so far — the question becomes whether he will face as tough a race in November as he did back in 2018. Six years ago, he beat Beto O'Rourke by just 2.6 percentage points, raising questions about whether Democrats could actually win a statewide federal race in the Lone Star State. But recently, his approval rating has notched up after being underwater for much of 2021 and 2022. On the Democratic side, Colin Allred is winning 62 percent of the Democratic vote with just over half the expected vote in.

In the Democratic primary for the Texas’s 15th Congressional District, Michelle Vallejo is leading with 32 percent of the expected vote in. She ran unsuccessfully for the seat in the 2022 midterms, but she’s leading her opponent, John Villarreal Rigney, 73 percent to 27 percent, according to The New York Times. Villarreal Rigney tried to run as the more conservative candidate, but Vallejo has the endorsement of much of the Democratic establishment and the pro-Israel group, Democratic Majority for Israel, or DMFI. AIPAC has endorsed her Republican opponent, the current incumbent, Rep. Monica de la Cruz. If Democrats can flip any seat in Texas, this is a likely one, making this race potentially competitive in November. Both AIPAC and DMFI have invested on the Democratic side to try to fend of progressive, anti-war challengers in Congress.

As Nathaniel and I discussed earlier, dynamics in the Texas state legislative elections have been particularly contentious this year, with the governor and Trump endorsing at least eight challengers to Republican incumbents in the state House. As of now, seven of those challengers are currently leading their primaries, though a few look headed to a runoff. One challenger, Barry Wernick in the 108th, is trailing by just 2 points.

ABC News projects that Biden will win the Minnesota Democratic primary, and Trump will win the Republican primary. Biden’s win is expected, but also salt in the wound for his highest-profile competitor, Minnesota Rep. Dean Phillips, who gave up a safe seat in Congress and the potential for a strong statewide run in a few years to launch his no-shot challenge against Biden.
