I don't think even Barry Goldwater could be nominated in the current Republican environment.
"When you say "radical right" today, I think of these moneymaking ventures by fellows like Pat Robertson and others who are trying to take the Republican Party away from the Republican Party, and make a religious organization out of it. If that ever happens, kiss politics goodbye."
I have a similar quote from Barry under my Democrat icon on Facebook.
"I don't have any respect for the Religious Right. There is no place in this country for practicing religion in politics. That goes for Falwell, Robertson and all the rest of these political preachers. They are a detriment to the country." - Barry Goldwater
