I don't know a lot about Pawlenty, but Romney seems to be someone that the country as a whole would find appealing. Actually, the person on the GOP side that would bridge gaps on the left and right might be Brown from Massachusetts. Guiliani self destructed last time, but he is another that would appeal to independents and the more conservative democrats, but neither of them is conservative enough to make it through the primaries. Too often the primaries become a series of crowning a candidate that perfectly matches the ideology of the party, bypassing the question of whether or not the person is electable in the general election.
