As described in an earlier post, Trump’s wins in the Northeast were already priced-in. No one who has been paying attention is surprised or impressed. This all comes down to two contests, neither of which are very favorable to Trump.
Trump has to score enormous wins in both California and Indiana in order to reach 1237 bound delegates prior to the convention. Take a look at this map projected generated on the website 270towin:
Winning in Indiana is not impossible for Trump, but that’s much tougher ground than Pennsylvania or Connecticut. Indiana is closer to Wisconsin or the midwestern states in its political character. Failing to win there sends him into a tougher series of contests without a knock-out punch. California’s size and diversity make it nearly impossible for anyone to sweep all of the state’s Congressional Districts. It still looks like tough sledding for The Donald.
