Most "conservatives" don't view the GOP establishment as being truly conservative. The Republican party is owned by the Chamber of Commerce and big money donors. They are big government and crony capitalists. They don't represent the people, and this is why Bush, McCain, and Romney didn't excite conservatives and were viewed as the 'lesser' of the two evils. Every time the Republicans run a 'moderate', the 'moderate' loses because there's no real difference between the parties besides some social issues. Democrats are just batshit insane to most conservatives.
Whatever dude it is your own damn fault.
The last person close to an actual Republican or Conservative by your criteria was Jimmy Carter, you all created this mess with Reagan and we all have been suffering for it ever since.
