Thats because the MSM have not dropped the boom on Perry yet, like they have done to Palin, Bachmann, Cain.
And the MSM will drop the boom on Perry as well. We will see how he holds up then.
He has been in office for more than ten years. It unlikely there is anything to drop.
No doubt about it, they'll ride him hard if they think he's a threat to their "chosen one" Mittins. My guess is he knows it's coming, and he's ready for it.
