The GOP isn't conservative.
They spend money like fucking crazy.
They want to use the government to control peoples personal lives.
They advocate using up nonrenewable resources and shit-talk renewables needlessly.
They aren't even holding to traditional values. Look at Donald Trump and ask yourself how in the fuck he embodies family values, excluding the values of a crime family.  
It's all just a story they tell themselves and their constituents. It's completely divorced from reality.
