The Hill asked a number of commentators to predict what happens in today's Republican and Democratic primaries. Here's what they had to say.
Winners: Trump and Kasich
Super Tuesday 2.0 is likely to be a very good day for Trump, and it could be a defining moment in the race. Trump will win Florida, North Carolina, Illinois and Missouri, netting his campaign in the neighborhood of 200 delegates out of a possible 367. That said, the main event is Ohio. Fortunately for the anti-Trump forces, Kasich will eke out a win in this winner-take-all state.
That leaves Trump as still the best-positioned candidate to secure the 1,237 delegates needed for the nomination, but to accomplish that he will have to win roughly 60 percent of the remaining delegates — a high bar, but certainly not impossible. Taking a step back and looking at the delegate math, a contested convention remains a 50/50 proposition.
