If Palin does not run (or waits too long), then we are screwed. Perry is our best alternative and we have half the freepers ripping the crap out of him with 15 year-old Texas Democrat talking points.
If he is our best choice apart from Palin, then let's vet him now, and find out what we can rather than wait for the MSM to blindside us after he has the nomination.
At least we'll know what we'll have to answer for if he is the nominee.
