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.

What Trump's edge in Virginia looks like

Trump looks well on his way to a clear victory in Virginia. With 46 percent of the expected vote reporting, he leads Haley 66 percent to 32 percent.

If we look at a map of Virginia's counties and independent cities, we can see how Haley failed to break through. To be competitive, Haley needed to perform well in the state's three major metro areas: Northern Virginia outside of the nation's capital, around the state capital of Richmond and in Hampton Roads, the southeast corner of the state. Yet she's mostly striking out so far.

So far, she only leads in the inner D.C. suburbs (including the state's largest county, Fairfax) and in the city of Richmond proper. She will probably gain as Fairfax reports more, but critically, Trump leads in Loudoun and Prince William counties, the other two big population centers in Northern Virginia. Trump is also ahead around Richmond and leads everywhere in Hampton Roads. And his strength in the rural areas is very strong, much as was the case in the 2016 GOP primary here. Haley holds leads in the city of Roanoke and in the Albemarle County-Charlottesville City area, but it's far from enough to make the race interesting.

Biden is projected to win in Vermont and Oklahoma

ABC News also projects that Biden will win in Vermont and Oklahoma, two of the states I'm watching tonight. Biden is a favorite to win across the country, but there is still a Democratic primary tonight.

Adding to what Galen said about primary coverage

I certainly don't mean to blame my hardworking friends in the media. The view from academia is that I organized a whole class around the prospect of an exciting primary, cue the sad trombone noise. I agree with what you said, and also think this is sort of an outgrowth of the weirdness of a primary election. Is it a preliminary election with terrible turnout? A party process, but just a fairly open one? It's hard for all of us in the explaining business because it's honestly kind of a confusing thing.

Trump is projected to win Oklahoma

This is not a surprise, but ABC News projects that Trump will win the Republican primary in Oklahoma, based on an analysis of the vote. In the latest polling, he lead by nearly 80 points against Haley.
