Mytheos Holt writes at the FrumForum:

It is on gay marriage where Cain takes more liberties. In fact, on gay marriage, he appears indistinguishable from Libertarian Rep. Ron Paul. Cain has refused to sign the Pro-Marriage Pledge, refused to support the so-called Federal Marriage Amendment, and has “Unknown stances” on every other issue the National Organization for Marriage (NOM) scores, other than defense of the Defense of Marriage Act, which every GOP candidate is on record supporting. In contrast, candidates like Michele Bachmann, Rick Perry and even Mitt Romney have openly said “Yes” to every question asked by NOM.

Given that Cain is perceived as the conservative standard bearer who has eclipsed more socially conventional candidates like Rick Perry, this raises an important question: Is Cain actually conservative enough for his support base, or are social issues actually in their twilight years?

Or is Cain in trouble if Iowa voters find out?
