Is Ron Paul Setting the Stage for a Third-Party Run?

Rep. Ron Paul announced today, via Tweet, that he will not be seeking reelection after 22 years in office. Instead, he says he’ll be directing all of his attention toward his presidential campaign:

“I felt it was better that I concentrate on one election,” Paul said. “It’s about that time when I should change tactics.”

The announcement comes as a surprise — even Paul’s congressional staffers only found out this morning, Reason’s Mike Riggs reports. And it’s left some, including Riggs, to wonder whether Paul will run as a third-party candidate if he loses the Republican nomination.
