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.
I know he’s been doing non-stop fundraising as it has to be done and will be key. Also, hopefully his back surgery hasn’t been an issue and he’s healed well.
His history says he will. In this country we love those that overcome adversity. If he gets on track in the debates he should be in good shape. As you say "it's up to him".
