No, I expect polls to continue to oversample Democrats. A random phone poll will always do that. Some pollsters will adjust the results, but others won't.
Obama did better. He beat Romney in the ground game. Polls are one thing, but your voters have to get to the polls.
Yes, Obama did very well: he had a higher voter turnout in some districts than there were known to be voting-age adults.
The same in Florida. He opened over 100 offices in Florida, many in the panhandle which is heavily republican. Obama knew he couldn't win the panhandle, but if he lost by 20% instead of 22%, he could win the state. He was correct. I think Obama won Florida by 70,000 votes out of 8 million or so. If 35,000 voters flip, Romney would have won Florida. Obama was much more strategic than Romney. He paid for it, too. We all paid for it.
