I didn't ask you about Romney. I asked about Obama. For now we will assume every negative thing about Romney is true. Why can't Obama break away?
Because he's a weak president that is only in a winning position because:
1. He's an incumbent
2. He's running against a weak challenger.
The fact that neither of them seem to be able to break away, and various polling organizations seem to barely put either man above 50% (in fact some have both at sub 50%) really speaks to how weak both are.
Romney can still win. But right now it's looking like Obama will get narrowly re-elected in the Electoral College. Romney hasn't make the case he deserves the Presidency yet to a majority of people, and sadly you can't win the White House on a platform of "The other guy sucks."
Even Reagan, running against Jimmy Carter, had more to his platform than "Carter sucks."
