Four points isn't much. I was listening to some talk radio (can't remember which one) early this morning and he was saying if Rick were to lose his home state of Pennsylvania it would ruin his political career. He also said that in 8 yrs. Rick would still be 3 years younger than Romney is now. He still has time and this race has really put him out there in the public eye.
Was hoping he’d stick it out through a Pennsylvannia win and string of victories in the south, just to show the GOP establishment that the real conservatives in the party aren’t buying what they’re selling.
