On Tuesday, more delegates will be awarded than on any other day of the presidential race. About half of the delegates needed for a Republican candidate to win the nomination are at stake, plus about a third for Democrats. In roughly a dozen state races, Republican front-runner Donald Trump and Democratic leader Hillary Clinton seem poised to win in landslides that could render them nearly inevitable.
Delegates, though, will be awarded proportionally, so challengers could use the day to position themselves for an extended fight, particularly on the Republican side, where states only begin winner-take-all delegate allocation later in March. Below, six predictions that suggest Clinton and Trump might be coming up on a very good day.
