Really? Where?
ETA: Based on polls, it seems like there's a fair number of libertarians, but based on conversations, it seems like it's 75+% hardcore, life-long, card-carrying, moral majority Republicans.
I wonder if some who would call themselves Republicans are really of a mindset that is more in line with the Libertarian platform. Many Republicans dislike the actions of the Democratic Party (and vice versa), but empirical evidence doesn't seem to show much of a difference in their core platforms.
