Are you kidding me? You really think Barry Goldwater, the father of the modern conservative movement, was a creationist? I think it's pretty clear that no Republican President, from at least as far back as 1870 to 1980 was a creationist. Reagan wasn't himself a creationist, but he said nice things about creationists around election time. And that's that -- the entire history of creationism in the mainstream Republican Party. Note the absence of support in any Republican organization for the State of Tennessee in the Scopes Monkey Trial. Note also the electoral disasters that have befallen Republicans, in Kansas and Pennsylvania notably, when they decide that the Republican Party is really the Creationist Party.
Creationism is a religious philosophy and it is completely appropriate within the confines of your Church. It is not a political idea and should have nothing to do with a political party.
It's either true or it's false. If it's false, it doesn't belong anywhere.
The "father" of the modern conservative movement? No wonder he lost. He didn't carry the religious right. You can claim that religion has no business in politics but just try and keep it out of politics. Even the demorats invoke it when holding hearings on judges. You want a government without religion? Then go to Russia. You just may fit right in. And just think, you can be happy with it instead of being angry about it being in politics here.
