GOP Candidate Gov. Rick Perry, R-Texas, is under an immense amount of scrutiny these days.

We know how much Herman Cain likes eating pizza, but Rick Perry really likes to give the thumbs up.

Even through the announcement of his tax plan on Tuesday, which has mixed reviews amongst the Republican party, Rick Perry smiles and gives his thumbs up.
