March 5 was Super Tuesday — the biggest election day of the year until the one in November! With former President Donald Trump projected to win 14 of the day's 15 GOP presidential nominating contests, former U.N. Ambassador Nikki Haley announced Wednesday morning that she is suspending her campaign.

It was also the first downballot primary day of 2024, with important contests for Senate, House and governor in states like Alabama, California, North Carolina and Texas.

It’s ovah in Minnesota

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.

Trump projected to win Massachusetts

ABC News projects that Trump will win the Massachusetts primary, his 10th win of the evening. With 15 percent of the expected vote reporting, Trump is leading Haley in the Bay State 59 percent to 37 percent. Yet again, this is another state where Haley was hoping to do well: Massachusetts has a lot of college graduates, and it allows independents and Democrats to vote in the Republican primary. But with Trump’s win, the Haley campaign turns its lonely eyes to Vermont.

Trump opens up lead in Vermont

With 56 percent of the expected vote now reporting, Trump has opened up a bit of a lead against Haley in Vermont. He has half the vote, and Haley is just behind him with 47 percent. Still, that's closer than the two polls, had us expecting. There's still room for Haley to pull out a win, which she would need: all of the state's 17 primary delegates go to the winner. That is, unless they both end up with under 50 percent of the vote, in which case they split the delegates proportionally.

More 2024 weirdness: The post-14th Amendment primary

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.
