Is there a consensus on whether Kasich dropping out would help or hurt Trump in securing a delegate majority?
Most people seem to think that Kasich staying in the race helps Trump, because Trump has an easier time winning plurality victories with a larger field, and most of the key remaining states are WTA by congressional district, if not WTA statewide.
However, I think the optimal scenario for the anti-Trump forces might be if Kasich stays in the race until after New York on Apr. 19th, or maybe after the other Northeastern states on Apr. 26th. If Kasich is in the race at that point, then he might prevent Trump from hitting 50% triggers in some of those states (or CDs). But once you get into May or June, then I really think the anti-Trump cause would benefit from Kasich being out.
