Bernie is on track to bag 180-200 of the 290 delegates at stake in the next 3 weeks and cut Hillary's margin to around 150-200 (1.300 vs. 1.100) by Mid-April.
If it weren't for the stubborn superdelegates and minority voters, it would be a real race ...
Except that, as has been mentioned elsewhere, nearly all of Bernie Sanders' win have been in the caucus states and they're over after North Dakota (which itself is a convention and not a caucus.)
With rare exceptions I think Hillary Rodham Clinton will handily win all of the remaining primary states.
Edit: except for the Wyoming caucus on April 9.
