OTOH, Carcieri has little to no name recognition, unlike Cheney, so it would be a much bigger sell than Cheney was.
Perhaps a US Senate run would suit Carcieri better.
I liked your argument. Carcieri would add gravitas to the ticket and shore up the areas where Bachmann is lacking. If she gets the nomination he should definitely be on the short list.
Of course, if she doesn’t get the nomination, Carcieri would ideal to recruit for a Senate race. He’s probably one of the very few Republicans that would be competative in RI.
