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

The former president's scorecard for endorsees is looking pretty good at the moment. Out of six candidates whom Trump endorsed, three have won their primaries (Mark Robinson for North Carolina Governor, Mayra Flores for Texas's 34th District and Tim Moore in North Carolina's 14th District) and two are leading (McDowell, who I just mentioned, and Brandon Gill in Texas's 26th District). We'll have to wait for the polls to close in California to see if Trump is heading for a perfect score.

Some Democrats have been pushing for voters to choose uncommitted on ballots where it appears, primarily to protest Biden's stance on the conflict in Gaza. However, as of now, it doesn't look like there's much difference between voters choosing uncommitted now versus in Obama's 2012 reelection campaign.

In Massachusetts so far tonight, 10 percent of voters have selected "no preference". That's the same as the percentage of Massachusetts Democratic primary voters that voted no preference in 2012. In North Carolina, Biden is the only name on the ballot, and 11 percent have chosen no preference. But in 2012, when Obama was the only name on the ballot in the state, there were 21 percent that voted no preference.

Other states have even lower uncommitted vote numbers. In Colorado, uncommitted has 7 percent of the vote, and it has 5 percent in Alabama and just 3 percent in Tennessee.

North Carolina now has more than 25 counties reporting most of their vote, so let the analyses begin! As in other primaries this cycle, the percentage of residents with a college degree is a strong predictor of which North Carolina counties are more likely to be supportive of Haley over Trump. That won't surprise folks who have joined us for prior live-blogs this election cycle. In Jones County in the eastern part of the state, a relatively low 16 percent of residents over 25 have completed a four-year degree (compared to an average of 24 percent across all counties in the state), and Trump has amassed a whopping 90 percent of the vote so far. It also looks like Trump does better in counties that are less densely populated, but we'll need to see more results to be sure.

I mentioned this earlier, but I'm tracking candidates endorsed by the anti-abortion Susan B. Anthony List. So far, the group can claim two likely victories: North Carolina House Speaker Tim Moore in North Carolina's 14th District and Rep. Mayra Flores in Texas's 34th District. Buckhout is leading in her race for the 1st District in North Carolina. The only Susan B. Anthony List endorsee we're tracking tonight who is trailing is state Rep. Grey Mills, who's in second place behind Rep. Pat Harrington. Harrington dropped a bid for the 14th District, where he would have faced Moore, to switch to the 10th. The 10th District's incumbent, Patrick McHenry, is not seeking reelection.
