Six months ago the likely opinion was that while Hillary Clinton would cruise to the Democratic nomination, the Republican race would be more hard fought, for while it had early front-runners like Jeb Bush, many figured to have a chance.

But where we sit today, the Democratic race is still competitive-- with recent polls showing Sanders with a national lead over Clinton --while Donald Trump appears to be on the precipice of running away with the Republican nomination.

What does this mean for the general election and the rest of the Democratic nomination? In basic terms, the question of how Trump will fare with the broader electorate is now less a joke, and more a matter of serious thought . And because he is increasingly looks to be the nominee in waiting, Democratic primary voters must consider electorability not in general terms, but with Trump as the likely opponent.
