Santorum probably won't run. He's been getting a lot of heat lately for an alleged affair with an illegal immigrant. If he gets through this unscathed he might run for his old seat in 2012. We'll see what happens.
I already said that he's basically ruled it out.
As for what you're talking about, that obviously isn't true. Make it something a little more believable (something that can't be disproven after a Google search) if you want to troll.
I'm only trolling if the guy who said that a senator would be outed was trolling. That senator was Larry Craig, not that he needed outing because he screwed up. I'd keep an eye on Santorum if I were you, he likes the men (especially non-English speaking men he can take advantage of), and it's not exactly a secret in certain parts of Pennsylvania.
This is not that out there. According to Internet rumor, 85% of American politicians share his like of men. The remaining 15% are lesbians.
