We commies have a problem.
We are dependent on the money of corporations and the votes of the masses. It's not our only problem. We have to hold together a coalition across tribe and culture.
Since they're dedicated to the end of civilization, it's a good thing the GOP has problems too. Gopers have to sign up for a set of mandatory untruths on science, history and economics for example. This makes it hard for the GOP to retain non-sociopathic rationals, much less secular humanists.
That's not their big problem though. Their big problem is theological. A party famous for intolerance has to pretend two quite different religions, Mormonism and Christianity, are the same. (Trust me, I'm an atheist. These religions have more in common than Islam and Judaism -- but not much more.)
This is a lot to pretend, but it doesn't seem as hard as, for example, worshipping both Christ and Mammon. It would be doable -- except for the Hell problem. Many GOP Christians believe in Hell, and they believe consorting with heretics is one way to get there. Mormonism is heresy; no doubt there. An eternity in Hell is a high price to pay for winning an election.
Maybe the GOP will patch this up -- but I think they're going to have to choose. They'll either have to offend Mormons and Romney supporters or offend their entire Christian Base.
Despite his current dominance, I don't think Romney will be the GOP candidate. If he is, he'll have a hard time harnessing the base.
If Perry is the alternative, expect Obama to ask if he'd have been welcome at Perry's *head ranch.
Considering the horrible odds against Obama's reelection he'll need more of this Irish luck.
