1. Well, no prizes for guessing this right. President Joe Biden and former President Donald Trump took big steps toward making their seemingly inevitable rematch official.

2.Trump wins big

The former president continued his run of dominance in the Republican nominating contest, despite losing one state, Vermont, to Nikki Haley.

3. Though the 15 states that voted Tuesday didn’t have enough delegates for Trump to clinch the party’s nomination for a third consecutive presidential election, he moved much closer, and demonstrated that the door for Haley is all but shut.

4.  The  delegate math: Just before midnight, with many votes still being counted, CNN’s latest delegate estimate showed that Trump had picked up 617 delegates on Tuesday to Haley’s 23. Overall, Trump had 893 delegates — 92% of those awarded so far and closing in on the 1,215 he’ll need to clinch the GOP nomination. Haley had just 66.

5. On Super Tuesday Biden has dominated his few rivals – typically winning around 80% of the vote. Trump, meanwhile, has rarely hit that mark. Haley, of course, is a more formidable challenger than Marianne Williamson or Rep. Dean Phillips. But Biden can only beat who’s on the ballot, and even with an estimable protest vote popping up in a number of states, the president clearly has the backing of his party’s rank-and-file.

6. In North Carolina, a swing state with a rapidly growing population of college-educated voters, 81% of those who backed Haley on Tuesday said they would not vote for Trump in November, CNN exit polls showed.
