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.

Jason Palmer’s PR team

I’m sure I’m not the only reporter who’s been receiving emails from Anderson Group Public Affairs, a PR firm flacking for Jason Palmer for several months now. I guess I should have been paying more attention before just sending them to my trash! Also, I think he’s the only candidate working with a PR firm that also sends emails with the subject line “Interview Entrepreneur Behind Billion Dollar Sex Toy Company.”

If you’re furiously Googling Jason Palmer right now …

You’re not alone. He’s currently trending on Twi—I mean X, and his campaign website appears to have crashed.

Tied again in Vermont

With 70 percent of the expected vote reporting in Vermont, Trump and Haley are tied again at 48 percent each. If Haley wins there, it might compel her to stay in past tonight, but the overall delegate math is still against her.

Book recommendation about U.S. territories

Want to know more about territories like American Samoa, which participate in the nomination process but aren't states — and thus don't have Electoral College votes or representation in Congress? I recommend this fascinating book, "The Not-Quite-States of America" by journalist Doug Mack. It explores the contradictions in the status of these areas and how it affects the people who live there.
