If Obama loses
Daniel Ellseberg has called on progressives living in swing states to vote for Obama.   Noam Chomsky (also no fan of Obama) has expressed similar sentiments.
If I lived in a swing state, I’d probably reluctantly vote for Obama.
If Obama loses by, say, 1%, I suppose Democrats will want to blame Jill Stein and Rocky Anderson, like they blamed Nader in 2000.
If Obama loses I’d be sad (because Romney and Ryan are definitely worse) but I’d say: “Hey, Obama. It’s your own fault. When will Democrats learn that they can’t win if they ignore progressives?”
The Dems can scream and point fingers all they want; it will be their own fault. Obama doesn’t deserve to win, any more than he deserved the Nobel Peace Prize.
They oughta have barf buckets on hand at polling places in those states.
