There is a lot to be encouraged about. He's been attacked by all sides and has not flip flopped on issues. His only weakness so far has been in the debates and once he gets his footing there he should start pulling away. Also, when it sinks in that Palin is not running he's going to look very attractive to the Palin backers.
Why all the talk about Christie if the rino's think they've beaten Perry back. They are recognizing Romney is not going to beat Perry.
Perry has withstood many broadside attacks...and he is still standing. But, this presents him with an opportunity and the country is watching.
He must stand up in debate and in his campaign nationally to redeem himself.
I think he was tired in the last debate (too much pressure with fires in Texas and his retail style of campaigning).
He must gather himself and demonstrate to the country that he can fight back.
I personally think this is what he excels at. But only he can demonstrate that.
