It's been a bit awkward:
Beginning an interview with MLive.com, a group of Michigan journalists, Romney was asked a simple question: "Tigers or Red Sox?"
"Oh, Red Sox, I'm afraid," Romney answered. "I've lived in Massachusetts for how many years now? Forty years."
Jon Cohn questions the supposed home-field advantage:
It’s not hard to imagine why Romney’s ties might mean so little. He hasn’t lived in the state since the late 1960s, right around the time his father stepped down as governor. Since that time, as far as I know, only one Romney has held public office: Mitt’s older brother Scott, who served as a trustee for Michigan State Univeristy from 2000 to 2008. During that same time span, the Romney family actually lost as many elections as it won: Lenore Romney, the family matriarch, lost badly when she ran for the Senate in 1970. Scott’s bid to be attorney general in 1998 failed, as did his bid for another term as MSU trustee in 2008.
