Whenever you have to tell people that you don't think people have to be smart to be president, how does that help ya? hahah

But then, he did tell people the LAST time he unsuccessfully ran that his brain was like a chicken pot pie

As Mother Jones says 

A lot of people think Texas Governor Rick Perry might be dumb. Perry does not think that should stop him from running for president.

That's Rick Perry-Lowering the bar from where George Bush raised it. 

Wonkette-Rick Perry Sure is Glad You Don't Have to be Smart to be President

Gosh, Gov. Rick Perry (R-Indicted) sure is eager to convince us that he is SO ready to run for president in 2016. He’s been practicing his counting and his ABCs, and he’s got those glasses, and he’s stopped popping pain pills, and this time, America, this time, we won’t be laughing our asses off forever and ever and some-other-word-we-can’t-remember-what about the comedy gold that was Perry’s last attempt to win the White House.
