First, the idea floated by Hillary herself that her supporters need some kind of "catharsis" before they can be convinced to vote for the presumptive Democratic candidate is patronizing (matronizing?) on its face. It's exactly the kind of notion that feeds prejudices about why a woman would make a lousy president: that a female is more likely than a male to sacrifice common sense and reason to the altar of emotion, and God help us if her finger is on the button when she's having one of her...days.
It's surprising that a woman as smart as Hillary would buy into that line. Or, maybe it isn't so surprising if you believe that she's really out for Hillary and that the whole "Joan of Arc of the Women's Movement" trope is just her vehicle for getting where she wants to be.
For those "dead-enders" (to quote Donald Rumsfeld, which I try not to do too often), who would rather vote for John McCain or sit on their hands than settle for half a loaf, I have three words: "Supreme Court nominee."
