Last night Ann Romney at the end of a long list thanked Kid Rock for helping her husband win the Michigan Primary. And last night Rick Santorum failed to thank Michael Moore even though Santorum's plea for Democrats to cross over and vote for him was a cause that the fat film-maker took up con mucho gusto.
Some people have speculated that the cross-over - voting as a joke - support was equal to about 6% of Santorum's overall total in Michigan. That 6% may get him a couple of delegates but it will in hindsight be the final nail in the coffin of his campaign. I hope the Romney campaign doesn't miss the opportunity to cudgel Santorum over the head with this issue. Stress things like "Santorum claims to be the real conservative in the race but then he looks for support from people like Michael Moore. Who does he think he is? Arlen Spector?"
Politics ain't beanbag.
