I ask you again - where are Santorum's anti-Romney ads, if he's so opposed to him?
Offstage and offhand comments by a candidate don't count nearly as much as their paid ads. Only those tell you who they're truly going after.
They aren't hard to find. You know about this ad because it's the first one Santorum has run, and the liberal media wants to let the world know, hopefully to keep conservatives split to help Romney. I see it is working for them, not that it's that hard to split conservatives these days.
Santorum ripped Romney(care) in the DEBATE, and it was HUGE!
Debates matter - that’s how Newt won SC.
Also, if voters are stupid enough to make Romney the nominee, which I doubt, Romney would pick RUBIO, imo, and here’s why:
