Inspired by Reihan’s wild imaginings and amused by this, I started thinking about McCain’s possible choices as a running mate (assuming that he is not on the verge of an unprecedented collapse and Huckabee is not at the start of an unprecedented comeback with Saturday’s wins).  As entertaining and implausible as a McCain-DeMint ticket sounds, a name came to mind that seemed a good choice to shore up McCain’s right, which almost immediately sank back into the darkness once I realised that it would become the cause of a thousand jokes at McCain’s expense (a happy outcome, if you ask me).  The name, of course, is Frank Keating.  Former governor of Oklahoma, Catholic, generally well-respected by conservatives as far as I know, Keating would make for a fine choice, but obviously putting his last name next to McCain’s on every sign and advertisement would not work at all.
