How can Republicans support Mitt Romney, after he Back and Ped RomneyCare?

This was a big problem Hillary Clinton Faced in the 2008 election's , She was slamming Republicans about the Iraq war as if she was opposed it from the start, when in reality she stood behind Bush and the Republicans. I think that was one of the main reasons she lost... Now I see a Mitt Romney, who authorized a Statewide Healthcare Bill. Which is virtually a carbon copy of National HealthCare. It appears almost Ridiculous to see him sitting on Fox News Slamming the President for something he did, at a local level. It's clear he is double talking. He's part of the establishment, Old School Republicans. Rather they want to acknowledge it or not, John Boehner, Newt Gingrich All those oldschool guys supported the Idea of a Individual Mandate during the 1990's. I as a Strong Christian Registered Independent , who has served this country in 2 wars. Strongly believe it would make more sense for them ( Establishment ) to come out of la la land, and acknowledge the error of their ways and try to move past it, rather than defend and slander and pretend to be someone they are not. The Movement of the mandate was started by the establishment, I will not sit here and Pretend, that Mitt Romney Does not support health-care, when he ped it in his own state ok? Stop telling me Mitt Romney is any different, I will not vote a faker into the Whitehouse, If you would vote for Romeny, you might as well Vote for Barack Obama again because at least he stands behind his ideology.
