It’s early still, but the returns look to show that Trump will come out pretty close to our projections, though may lose a few delegates in Illinois and a few more in Missouri. It’s limited data, but the returns suggest Trump’s ceiling correlates closely to his poll numbers. With that and Rubio’s drop out, our model shows Trump missing a win by around 150 delegates – particularly if Rubio (and perhaps Bush) throw some weight behind Kasich. Big asterisks: Kasich still might not end up on Pennsylvania ballot.
On the Democratic side, Clinton appears to be exceeding our projections slightly, particularly in Ohio and Illinois (and, of course, Missouri, where we had her losing by nearly 10). This suggests her polls need to add somewhere near a one-third take of the undecideds (vice the worst-case 0% we projected). This still has Clinton short exactly 100 delegates from an outright, no-superdelegate win, but she finds herself in a much stronger position.
