Does Clinton want to lose this election?

I don't think she's conscious of this self-sabotage. Like all the other corporate Dems she thinks all the progressives will just come along for her given the nightmare that is Trump. But with Kaine as her VP pick she has just pissed off many, if not most, of the very progressives she needs to win this election. Kaine supports the TPP, off shore drilling, fracking and Wall Street deregulation. While Clinton has said she's against all that, her VP pick does just the opposite and is a better indicator of what she'll do in office. Yes, the pick placates the corporate Dems and their Wall Street overlords, but it certainly only gives the millions of progressives further ammo to vote elsewhere. These establishment Dems are just in such a bubble that this costly mistake might just elect the Hitler on the other ticket.
