Everyone's talking about how the guys are ganging up on Hillary, though that's what happens to frontrunners. But Hillary's recent drop in the polls opens up an interesting question. Even without the aura of invincibility, she still looks like she has a solid lead, but what happens if one of her two main opponents drops out? Hillary's commanding lead is still just a plurality. If most of the other voters are anti-Hillary, the last man standing has a reasonable shot.
