Perry was up to 4th place a week or two ago and it was ignored. You didn’t hear all the surge talk when he had movement. Same with Newt, if he starts to recover, they totally ignore it.
Secondly, I haven’t heard Obama’s people attack Romney but either way, they are not afraid of him. He can’t fight Obamacare because he started it. He’s a liberal so the Republican base would sit home and O would steal yet another election. Obama would love to face off with Romney
