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

ABC News is projecting that Biden and Trump will win their respective presidential primaries in Texas, as will Republican Sen. Ted Cruz, who Democrats are angling to unseat this fall. The race for the Democratic Senate nomination in Texas is hot, though as I mentioned earlier, the front-runner is Rep. Colin Allred, a former NFL player and civil rights attorney who has represented the Dallas area since 2019.

Trump projected to win Texas, Arkansas

Former President Donald Trump will win the Republican primaries in Texas and Arkansas, ABC News projects, based on analysis of the exit poll.

Based on an analysis of the vote, ABC News projects that Trump and Biden will win their presidential primaries in Arkansas. With about 7 percent of the expected vote in, Womack is holding onto his lead in the 3rd Congressional District 60 percent to 40 percent against Penzo.

I'll be very interested to see, when the dust settles tonight, if the polls are more on the money in states with closed primaries, where bored (or wily) Democrats can't vote in the Republican Party primary for Haley. A lot of the exit polling data we've seen on Haley supporters and who they'll vote for in the general election, or whether they approve of Biden's job performance, makes me wonder how many of her voters are just plain old Democrats who are getting screened out of a lot of GOP primary polling. But we'd see a difference in closed primary states (to the extent we have robust polling there to make the comparison)!

Julia, I'm suspicious that the reason Trump's lead in primary polling has been somewhat exaggerated is that pollsters are not necessarily capturing some of the independents who are showing up to vote in a GOP primary. As Nate Cohn recently pointed out in The New York Times, some pollsters have filtered for likely GOP primary voters by mostly or only looking at voters who've voted in Republican primaries. But a fair number of independents, including Democratic-leaning ones, wouldn't necessarily fall in that category. But with Biden a lock to win the Democratic nomination — barring something happening outside of the voting booth — Democratic-leaning voters have only one race to get involved in. Although we know there aren't that many "cross-over" voters who participate in the opposing party's primary, some high-propensity Democratic voters and some Democratic-leaning independents have probably voted in states that allow non-Republicans to cast ballots in the GOP primary.
