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.

Haley quotes Thatcher and thanks the women and girls who supported her campaign

In her short remarks, Haley quoted Margaret Thatcher: "Never just follow the crowd. Always make up your own mind." She used this quote to encourage the likely nominee, Trump, to appeal to the primary voters who he hasn't won over. She also thanked the girls and women who have supported her campaign, as another (subtle?) reminder of her historic run.

Good morning!

After a full-ish night's sleep, we're back on the live blog as the winners of several House primaries from Super Tuesday remain unknown.
