The only possible way Romney can win in November if he's the nominee is for the USSC to uphold all or even part of Obamacare.
If nothing of Obamacare remains, people will figure they can take the Senate and keep control of the House so, screw Romney. They'll figure a Republican House and Senate can reign King Barry in and roll things back. The problem is, unless it's two thirds control, it's still a holding action until there are enough votes to override a veto. Of course, if Romney starts talking about "fixing" Obamacare rather than eliminating it, then Barry will be good to go for another four years anyway. He'll also be on track to impeachment for one or more things he does by executive order, but to Barry, that's the best possible outcome short of the super-majorities he had for the first two years.
If the USCC retains even part of Obamacare, Barry is toast in November. It'll be the Carter hostage crisis with the entire population as the hostages and everyone, even the dimwit dolts who sway in the breeze, will know it.
JMHO
Very astute analysis. I agree with you.
I truly do not believe there are that many people who really give it that much thought or even have that thorough of an understanding of how our government functions.
