Are Republicans losing their minds?

In a word, yes. Sadly. As Slate's Jacob Weisberg observes, before any GOP official utters a word in public,"he must constantly ask himself the question: Am I about to say something to which a white, evangelical, socially conservative, gun-owning, Obama-despising, pro-Tea Party, GOP primary voter in rural South Carolina might object? By this standard, simple acceptance of the theory of evolution becomes a risky stance. To lie or to duck?" The truth rarely enters the equation. "Conspiracy thinking is flourishing on the right like no time since the McCarthy era. The GOP rank and file is in desperate need of a cold shower, a slap in the face, a wake-up call. But instead of telling the base to get a grip on reality, the party's leaders are chasing after the delusional mob. To get to the front of the line in 2012, Republican candidates must pretend to believe a lot of nonsense than isn't so."
