All the recent talk of an Obama-Clinton ticket would be more distressing if I thought it was more than a desperate PR move by Hillary’s campaign. Obama has to be smart enough to know that would be a lose-win non-partnership, and the worst possible tactical move for his own candidacy. Her recent remark about Bobby Kennedy takes her down yet another notch. Like the Economist, Kos and many others, I say it’s well past time for her to hang up her hat and spend some quality time with ol’ Bill.
