Although Bernie has been in politics a long time and could certainly fall in the realm of 'career politician' he still seems to try and fight the fights that need fighting; he hasn't fallen the way most career poli's go … even if he doesn't get all the support. At least with him in the race, he keeps issues relevant. Even if he doesn't get the nomination, he's going to shake things up. If Biden jumps in, it tells me one thing … the Democratic party leadership (Kerry, Ried, etc) are afraid of BOTH Sanders and Clinton for one reason and one reason only … neither one will cowtow to them, neither one will be 'controllable' by them. In the end, and I've said this before, as a woman, I have too much at stake and will never, ever vote for or want a Republican in office to oversee the next Supreme Justice nomination. I will vote Democratic every single time … even if it means Hillary or Sanders … whom I both like, or at least don't hate. But even if it's Biden (barf) I'll vote for him, too. Voting against the current Republican party will always be the way I vote until it changes.
