To those who say Pawlenty is not interesting, I'd ask:
Who else can win all the GOP constituencies?
I think that anyone except Palin can count on all GOP constituencies to come home in November 2012. Even Huckabee would get their reluctant support, it's the nature of polarization these days. The question is to what extent people will be enthusiastic. There are concerns that Romney will dim enthusiasm among some cultural conservatives. What I would say is that it's hard to see Pawlenty inspiring enthusiasm among anyone--something other Republican candidates can do. And I don't see him winning over independents on anything but a generic R basis.
