If Mittens wants to win, all he has to do is Dummy Up. He’s gotten away with it this far already and he can’t defend his record because its indefensible.
There are far too many self described centrists, moderates, and know nothings in the US today. If Romney just keeps playing stupid he’ll win because he can then blame the failure of his own policies, which are virtually identical to Obama’s, on the Other guy whose currently implementing them.
There is so much truth in this -- a Conservative would have to educate this populace to win.
Mittens merely has to say, "Here's what I would have done differently over the past four years..." ie focused on private-sector job growth instead of implementing nanny-state government.
