Is there any proof of that? Romney is scared to take even a moderate position, let alone a conservative one. Even though he knows it will cost him the election he still won't even pretend he's against socialized medicine.
I would say working in the private sector successfully would offer a modicum of support to the idea he is a capitalist.
Romney has stated repeatedly he will repeal Obamacare, you are certainly free to disbelieve, but you know for a fact Obama will not repeal it.
And as I have also stated, giving Obama any more Supreme Court nominations would be a disaster.
