Not everyone who isn't on-board with Paul is a neocon. Very few are, in fact.
Taft may not matter to conservatives, because they don't really know what he stood for. Goldwater is a different story. Reagan, even more so. I think a very large number of conservatives want someone with the principles that Reagan espoused. They were the same as Goldwater's. Problem is, they aren't *hearing* those things from Dr. Paul, so they don't recognize that what they want so badly, is right in front of them.
I know that. But the neocons have completely infiltrated the Republican party. They were non-existent for awhile. They were strongly opposed to the wars in Bosnia. Post 9/11 changed the GOP so much.
Reagan was a massive spender and one of the biggest feeders of the War on Drugs. I don't get the obsession with him. Possibly the most overrated GOP president (sans Lincoln).
As for Goldwater, I've heard his name disparaged so much. I went to a speech by Ann Coulter once, where she said the reason why GOP loses elections is when they nominate moderates like McCain, Dole, and GOLDWATER. Yes she claimed that Goldwater's views were out of line with the republican party and was luck to get the GOP nomination. For whatever God knows what reason, many Republicans LOVE Coulter.
