one thing about Giuliani/Romney is that maybe just maybe Romney puts both MA AND MI into play....are his conservative bona fides enough to give conservatives some hope with Giuliani at the top?
My thinking is that Santorum helps Giuliani with religoius conservatives...I don't know if Romney does that. Evangelicals especially like GWB's piety. I don't know how the Mormon thing will go over.
Thing about Mitt is that he's a conservative Mormon who won the governorship of MASSACHUSETTS. That's not small feat for a Rep, much less an openly religious guy. The appeal to the Christians isn't denomination, it's honest piety. With G at the top of the ticket, you get the center/right spread and groom a nice solid conservative for the spot in '16.
