Even Senator Clinton seems to have acknowledged this in her statements of support yesterday. I'm glad she's around in case Barack gets hit by a meteorite, but you don't build credibility by claiming "it's still an open race" when it just isn't.
Senator Clinton has a lot of support still, and this must buoy her spirits. I'm really pleased with how things are going now that she seems to have backed off the "electability" attacks. (Although someone needs to hit Bill with a cluestick...)
It's just an outdated abbrevation from the women's movement of the 1970s. It's still a valid criticism, just the term has faded. Tron was quite a while ago, too, but clearly it stuck in our minds a bit longer. :-)
