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

In Arkansas, Justice Courtney Hudson won a race for position 2 on the state Supreme Court. She currently holds position 3, but ran for the vacant position 2 because of complicated judicial retirement rules. Her win will leave her current seat vacant, which will give Sanders the opportunity to appoint a replacement for the rest of the term. There is also a 4-way race for the chief justice spot, but if no candidate wins a majority tonight, the top two will head on to a runoff in November.

With nearly all expected votes counted in the Republican primary for North Carolina’s 10th District, it’s a tight race between moderate Pat Harrigan, who has 41 percent of the vote, and conservative Grey Mills, who has 39 percent. Whoever wins will be heavily favored to win the general election in this dark-red seat, which is open because Rep. Patrick McHenry is retiring.

In the Republican primary, attorney Caroleene Dobson is trailing businessman Dick Brewbaker in Alabama’s 2nd district, with 40 percent of the expected vote reporting. This race is an open primary due to redistricting, where eight Republicans are running for the nomination. Dobson had received an endorsement from VIEWPAC, an organization that formed in 1997 to elect more Republican women to office.

Back to regularly scheduled programming ... Former Tennessee Titans linebacker and current Congressman Colin Allred is projected by ABC News to win the Democratic primary for Senate in Texas.

Allred was the favorite to win the race tonight, but the bigger challenge will be trying to unseat former Canadian and current Senator Ted Cruz this fall. As Dan noted when Cruz locked down his primary earlier tonight, Democrats are hoping that they can finish what Beto O’Rourke started in 2018, when O'Rourke came within spitting distance of flipping Cruz’s Senate seat. If Democrats' are going to flip any Senate seats, this is likely their best shot, and is an important one if they hope to maintain their narrow majority in the upper chamber. So expect to see a lot of eyes and cash on this race in the months to come.
