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

538 tracked how Trump and Haley did, plus key U.S. House and Senate races.

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.

538 reporters, analysts and contributors broke down the election results as they came in with live updates, analysis and commentary. Read our full live blog below.

Davis probably would have preferred Smith

Smith is an outspoken, MAGA-style firebrand who hasn’t managed to pull out a win in the area and would have been a more appealing (read: weaker) opponent for the freshman congressman in this swingy district. As I mentioned earlier, the 1st District has long been a Democratic stronghold — it hasn’t elected a Republican in over 140 years — but after redistricting, it was redrawn to become a tossup district, and is set to be the only real competitive Congressional race in North Carolina this fall.

AP projects a winner in North Carolina's 1st Congressional District

In North Carolina's 1st congressional district, Buckhout is projected to win the Republican primary, according to The New York Times. We wrote about this earlier, but her win comes on the strength of national Republican Party efforts to make her the nominee over two-time candidate in the district, Sandy Smith, a candidate with a more Trumpy profile. Buckhout will take on Democratic Rep. Don Davis in November.

Where's Trump doing especially well in North Carolina?

With more than 90 percent of North Carolina's expected vote in, we can now say more about the patterns in that state. First, Trump is romping statewide, with 75 percent to Haley's 23 percent. But where is Trump doing especially well? In counties with few people with college degrees, sure. But also in counties with lower population density and more Black voters. That said, it doesn't mean Trump is doing well with Black GOP voters — preliminary data from the North Carolina exit poll suggest that in fact non-White Republican primary voters were a bit less supportive of Trump than white Republican primary voters. Instead, Trump is doing especially well in the counties with more Black residents (regardless of whether they're voting tonight or not).

The establishment candidate may endure in Kay Granger's district

With 81-year-old Rep. Kay Granger set to retire, the primary race to replace her in Texas's 12th District looks like it may go to the more establishment GOP candidate: state Rep. Craig Goldman, who is currently leading with 46 percent and 78 percent of expected votes in. He'll need to get 50 percent of the vote (plus one vote) to avoid a runoff with local businessman John O'Shea, a more Trumpian candidate who currently has 25 percent of the vote.

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.
