When it comes right down to it, Gingrich and Santorum have both spoken quite kindly of each other. Most of the animosity comes from the superpacs and supporters.
While saying that he would consider Gingrich as a VP choice, Rick Santorum calls Gingrich a true conservative who fits the bill.
If he gets the nod, Santorum could do a lot worse than Gingrich on picking a VP. I know Gingrich has his personal faults and failings, but he is very smart and has ideas and plans that can turn this country away from the ruinous socialist path it is on now. We need people in power who can fix these problems, even if they are not saints in their personal lives (who is?). I know that sounds a lot like Clintonian rationalization, but at this point I must confess I am desperate enough to get Obama out of office and turn this country around that I am willing to look past those things to the more immediate and pressing need, which is to save and restore the Republic that our forefathers have bequeathed to us, and is in grave danger of being squandered and bankrupted by Obama and his socialist minions.
