I agree with you and as much as I like Perry, I fear that he has been forever tainted by his bad performance in his last bid.
The public was heartless as to his back surgery and resulting gaffs.
He NEVER told the viewers he had back surgery and was on medication. All of his gaffs can be blamed on his bad politicking.
One of the reasons he probably isn't running for reelection as governor is that he can't get elected----Texans NEVER knew until the presidential debate that he had given illegals in-state tuition.
Perry is the one that told the electorate WE were heartless WRT amnesty.......making us the villains and himself the good ol' latino suckup boy.
The way he entered the prez race was an outrage---he never campaigned---but he stopped the momentum of Michele Bachman who actually won the primary. Perry acted like he had won---plastering himself allover the media w/ that snarky Texas grin.
