You're forgetting one important distinction...they're nuts, and we're not.
And I'm not kidding. I think parallelism is a mistake. Plurality wins just as surely as majority. We will NEVER have a majority, but we've already got the plurality. And by "we" I mean conservatives, not republicans.
Question.
Did you ever hear of a man called Ronald Reagan?
He was a governor of a state that is widely known for its liberalism and he was a conservative. He then ran as president as a conservative, governed as a conservative (despite a mostly democrat congress) and then won a second election in a landslide with 49 states (out of 50, in case you needed some perspective).
Rick Santorum won as a conservative. He's behind now that he is not. BTW, his faux conservatism became apparent when he help to defeat a real conservative by helping one of the most liberal Republicans.
Ron Paul, a libertarian Republican wins in a mostly democrat district by standing solidly on the Constitution. Tom Coburn is a solid conservative and won in a majority Democrat district. He term limited himself in the House and then ran for the Senate and he was elected as a conservative.
The problem isn't that America doesn't lean conservative, but that the GOP crushes conservative candidates in the primary.
BTW, when Santorum came from behind it was (again) when he ran as a conservative, voted as a conservative, and had the hearty support of conservatives.
In the last 2 years, his record sucks and he has alienated his base on just about every issue. He still talks a good game, especially at fund raisers, but his actions fail to back up those words.
He claims to be pro life but supports pro abortion candidates whose votes negate his. He claims to be pro gun, but supports gun grabbers who cancel out his vote a lot of the time even though he is only 'with us' 64% over the last ten years.
He claimed to be a conservative, but has since emulated the 'compassion' of Senor Bush and the spending habits of Arlen Specter.
His last victory was by less than one percent. He has lost the support of many of those who get out the vote and give him money.
Don't count on a 'comeback' this time. He dug his own grave and dared us to push him into it.
