So John McCain will be endorsing Mitt Romney in New Hampshire. It is the logical circling of the wagons around the shaky frontrunner Republican leaders hope will be the nominee. But it seems to me that Romney doesn’t need much help among the voters who would be impressed by a McCain endorsement — I think he has a surprising number of McCain 2008 voters already — while the endorsement reminds disaffected conservatives of what happened the last time they ignored their concerns about a Republican’s conservatism.
