The reasons RR Reno worries about it:
First, religiosity now strongly correlates with partisan loyalty. Nones are overwhelmingly Democrat. Regular churchgoers, especially but not exclusively Evangelicals, trend Republican. This politicizes religion. Second, religious people are becoming more and more dependent on the Republican party to protect their interests (religious liberty, for example). We could easily become a taken-for-granted base largely irrelevant to the party’s larger policy debate, as African-Americans often are in the Democratic party. Third, religion, especially orthodox Christianity, may end up implicated in the inevitable failures and corruptions of the Republican party. We may be in danger of recapitulating in some ways the disastrous alliances of the Catholic Church with the European right in the nineteenth and early twentieth centuries.
Douthat wonders if Pope Francis could help Christianity avoid this fate:
I think this analysis suggests a positive case, in the American context at least, for a papacy that simultaneously calls U.S. Catholics away from a too-close entanglement with the fortunes and platform of the Republican Party, and that consistently reminds non-Catholics and non-Christians that there is more to Christianity than the particular set of issues that have (understandably) kept many American believers in a right-of-center political orbit.
