Nonsense. A full 48% (or more) of registered voters will never vote for Obama. A wet dish towel can beat Obama. Its more a matter of who will make the better POTUS: Obama-lite Mitt, or Newt.
I have said this for months the GOP is picking the President not the nominee. Obama has no chance to win this cycle.
1. There were a lot of young people who thought it would be "cool" to have Obama as president. That novelty is GONE because on the one hand they've already done it and on the other hand they are now out of college and struggling in the Obama economy.
2. Blacks wanted a black president. But he hasn't done anywhere near what they expected. Many of these voters had never voted before and probably never will again.
3. Upper-middle class white voters looking to overcome white guilt viewed voting for a black for president as "something they needed to cross of the list," but now that's over and the reality of their personal financial prospects has kicked in.
