Update 12:22 p.m.: Perry's announcement via Twitter that he's still in the GOP race reveal something curious about his campaign: he personally runs his own Twitter account. Politico spoke with some Perry advisers, such as Mark Miner and Joe Allbaugh, who first learned of Perry's decision to stay in from his tweet.

Update 12:03 p.m.: National Journal's Ron Fournier and Rebecca Kaplan confirm beyond the tweet that Rick Perry is staying in the race after talking to an anonymous campaign official.

Fifth place in Iowa apparently isn't deterring Rick Perry just yet, as he's now tweeting that he's moving on in his campaign to South Carolina. "And the next leg of the marathon is the Palmetto State...Here we come South Carolina!!!" writes @GovernorPerry before posting a picture of a wetsuit- running-outfit-clad Perry in front of a body of water. Last night, in Iowa, Perry certainly did not sound like he was up for much of anything after his disappointing finish. "With the voters' decision tonight in Iowa, I decided to return to Texas, assess the results of tonight's caucus, determine whether there is a path forward for myself in this race," he said in his concession speech. And all sorts of Perry camp sources were telling reporters that this was the end for him. One Perry staffer in South Carolina told CNN on Tuesday night, "It looks like he is not coming this week. He has definitely canceled his plans." Perhaps Bachmann's decision to drop out made Perry change his mind. Maybe Romney asked him to do him a favor and stay in the race to siphon support from Santorum. We don't know. And we also aren't exactly sure what this has to do with the photo above.
