That is the question posed by a post over at the CNS News Hub, which links to articles in the other NCR (the Register) that say, first, that McCain is not, then with a response from Senator (and convert) Sam Brownback saying he is. This is likely to be an ongoing debate, and McCain would seem compelled to address these concerns to shore up the right (and the "Catholic" vote?). Then again, McCain doesn't like to be pushed.
