I am not at all sold on Newt (b/c of AGW) However, Santorum has zero charisma and will NOT win any more primaries, or even come close.
Of those remaining, Newt is best suited to defeat the Statists: Mitt and Obama.
So that is what Newt exudes? Charisma?
The head to head shows Santorum crushing Romney. Newt would lose in a two man race.
