Texas Gov. Rick Perry is staying in the presidential race despite a fifth-place finish in the Iowa caucuses.

He's written on his official Twitter account that the "the next leg of the marathon is the Palmetto State. ... Here we come South Carolina!!!"

He's attached a photo of himself jogging near a lake, wearing a Texas A&M running shorts and showing a thumbs-up.

The South Carolina primary is Jan. 21. New Hampshire's is next Tuesday.
