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.

Lots of voters aren’t paying attention yet

I think that's right, Galen. In a CNN poll back in January, 35 percent of voters said they either don't follow the campaign at all or only pay as much attention to it as necessary. Another 38 percent said they don't seek out campaign news, but do follow the news that they encounter. Only 26 percent of voters said they are frequently seeking out news about the campaign. At this point in the race, voters are not really tuned in. It may be that whatever happens in the primary stays in the primary.

Endorse Julia's frustration with conflating the primaries with the general

Julia, I hear what you're saying, and as a member of "the media," I have an inkling as to why this is happening. The primary contests are not competitive and we have to talk about about ... something ... anything!

To echo what you're saying, just 22 percent of the registered voters in Michigan cast a ballot in the primary last week. In 2020, voter turnout exceeded 70 percent in the general. These are just wildly different electorates.

I often feel flummoxed by comparisons of the midterms to the general, and in the midterms turnout is closer to 50 percent. A general electorate is far less engaged in politics and is — according to polls — more driven by economic issues. And frankly, a big chunk of them find both Biden and Trump unappealing.

So, while I do think there are interesting things to say about the primary, they are not the kind of things that will tell you who will win in November.

Republican leaders really wanted Buckhout

The Congressional Leadership Fund, which is aligned with the Republican House leadership, has spent several hundred thousand dollars to prevent Sandy Smith from winning that primary again. CLF also spent (unsuccessfully) against Smith in the 2022 primary after several damaging stories about her came out.

Buckhout is very wealthy …

Not only did she drop more than $1 million of her own money into her campaign, she lives in a fancy, columned, waterfront manor in ritzy Edenton, with its own boat dock and putting green!

Haley’s favorability ratings in Super Tuesday states aren’t encouraging for her

While we don’t have data for every Super Tuesday state, in the ones we do, Haley’s favorability lags far behind Trump’s among Republican voters. In Texas, an early February poll from YouGov/The University of Texas shows GOP voters there have a particularly dim view of Haley; the survey shows Haley 4 percentage points underwater among Republicans, with a 36 percent favorability rating and a 40 percent unfavorability rating, while Trump is has a massive positive net approval rating of 71 percent (83 percent favorable and just 12 percent unfavorable).

While not quite as dismal as in Texas, Haley’s numbers in other Super Tuesday states lag far behind Trump’s. For example, a Morning Consult/Bloomberg poll from mid-February in North Carolina has Haley at net +18 percent favorability (52 percent favorable, 34 percent unfavorable) among registered Republicans, compared to net +64 percent favorability for Trump (81 percent favorable, 17 percent unfavorable). An early February poll in Maine from Pan Atlantic Research shows Haley at net favorability +15 percent favorable (50 to 35 percent), compared to Trump’s net +52 percent favorability rating (76 to 24 percent).

In Vermont, polls suggest Haley might perform a little better than in other states, but her favorability is underwater, according to an early January survey from the University of New Hampshire Survey Center. That survey had Trump with a lower favorable rating than he enjoys in other states, net +20 points (57 to 37 percent), but Haley had a net favorability of -9 points among likely primary voters: 32 percent favorable and 41 percent unfavorable.
