Yesterday, the Supreme Court rejected the legal arguments claiming that Trump could be disqualified from running for president in 2024 because of his connection to the Jan. 6 insurrection at the U.S. Capitol. Section 3 of the 14th Amendment states that anyone who held a public or constitutional office and has engaged in insurrection is ineligible to hold office in the future, unless Congress passes a law stating otherwise. Section 5 says that Congress can also pass laws to enforce any of the provisions in the amendment. Lawsuits in several states came forward to disqualify Trump on these grounds.

But until recently, very few people had given much thought to this part of the 14th amendment since the years immediately following the Civil War. Legal scholars brought up a couple of ambiguities — did it apply to the presidency, since a number of offices are named, but not the president? Do we have an agreed upon definition of what counts as participating in an insurrection and whether Trump did that in 2021? (Spoiler alert: No.)

The Supreme Court ruled unanimously that the state of Colorado could not disqualify Trump, though there were disagreements about how far to take that ruling. A majority held that Congress would need to pass a law in order to enforce Section 3. Though the unanimity of the ruling papered over some of the partisan politics, the timing was impossible to separate from political considerations, since it came just in time for today’s big round of contests.

ABC News can project that Tim Moore has won the GOP primary for North Carolina’s 14th District. Moore is the speaker of the state House and played a role in redrawing North Carolina’s congressional map this cycle to give Republicans three new safe seats — including one that included Moore’s home base. Unsurprisingly, he jumped into the race and faced only nominal opposition in the primary, and he should easily win the general election as well in this Trump +16 district.

Some of those races to watch in North Carolina are still cooking, and I have a hunch we may end up in runoff territory for a couple. In the 1st District's GOP primary, Laurie Buckhout is edging ahead of Sandy Smith by 4 percentage points, with 34 percent of the votes in.

In the 6th District Republican primary, it's an incredibly close three-way tie right now between Trump-endorsed political newbie Addison McDowell, former Green Beret Christian Castelli, and former Rep. Mark Walker, who represented the district from 2015-2021 before making an unsuccessful bid for the Senate. Bo Hines, a former wide receiver for North Carolina State University who ran unsuccessfully in 2022, is trailing the other three. This race will determine the winner in November — there are no Democrats bothering to run in the 6th, since it was redrawn to be much redder.

And in the deep-red 8th District outside Charlotte, redemption-seeking former nominee Mark Harris, whose 2018 congressional win was thrown out due to allegations of ballot fraud, is just barely leading Allan Baucom, a farmer and former chairman of the Union County Board of Commissioners. State Rep. John Bradford, who has poured $1.3 million of his own money into his campaign, is trailing with 81 percent of votes in.

Remember that in North Carolina, if no candidate gets 30 percent or more of the vote today, races will go to a two-candidate runoff in May.

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.

The race for Senate in Texas will surely be one of the most closely watched races of the year. There are nine candidates running in the Democratic primary to unseat Sen. Ted Cruz, but the front-runner is Rep. Colin Allred, a former NFL player and civil rights attorney who has represented the Dallas area since 2019. Allred has raised the most funds (to the tune of $21 million) and attracted donations from party influencers. The biggest question tonight is whether Allred can pull more than 50 percent of the vote and avoid a May runoff.

There are also a handful of U.S. representatives in Texas with at least some danger of losing their seats tonight, as Jacob covered earlier. Keep your eyes on Houston Democrat Lizzie Fletcher in the 7th District, who is facing a challenger from the left in Pervez Agwan; Democrat Sheila Jackson Lee in the 18th District, whose run for Houston mayor last year destabilized her campaign against former Houston City Councilwoman Amanda Edwards; and Republican Tony Gonzales in the 23rd District, who is facing multiple challengers and may also end up in runoff territory.

And there are some open seats up for grabs, creating hotly contested primary races. In the 12th District around Fort Worth, it's the familiar GOP battle between results-focused conservatism of the old guard versus the firebrand populism of MAGA. State Rep. Craig Goldman represents the establishment candidate, while business owner John O'Shea fills the role of MAGA candidate. In the 26th District, two far-right candidates are leading a slate of 11 to fill the open seat in this deep-red stronghold: Brandon Gill, who heavily promoted his father-in-law, Dinesh D'Souza's, conspiracy-theory-laden film "2000 Mules" on his website, and Southlake Mayor John Huffman. And lastly, with Allred making a play for the Senate, his Dallas-area 32nd District is up for grabs. Ten Democrats are running in the primary, though two in particular seem to be leading the pack: state Rep. Julie Johnson and trauma surgeon Brian Williams.

If you're interested in reading more on these races, check out my full preview from last week. Otherwise, I'll have more on these races and other takeaways from Texas after polls begin to close there at 8 p.m. Eastern.
