No one asked me, but I just want to briefly weigh in on the question of whether the increasingly brutal primary process will hurt Mitt Romney in the general election. No. It won't. Voters will forget the debates even happened about ten seconds after the last genuine competitor (i.e., everyone except Ron Paul) drops out. Intra-party feuding will stop about ten seconds after that, when everyone remembers that Barack Obama is Hitler. And the Obama campaign itself, though I'm sure they're enjoying the bloodletting, probably had better versions of all the anti-Romney attacks already prepped and ready to go before the first GOP primary even got started.
Any other questions?
