Obama won by healthy margins in '08 and '12, and Hillary – the least likeable candidate that’s made it to the top of the Democratic ticket since Dukakis – still won the popular vote. I think the people who would vote against a black woman for President were never going to vote for a Democrat in the first place, and given the general aura of relief and enthusiasm I’ve seen in left wing spaces since the announcement I think Harris is going to be riding a wave of support from the left, even if half of it is just from people who are glad they don’t have to hold their noses to support a doddering octogenarian because the alternative is fascism.
