Rep. Trey Radel, R-Fla., will resign from Congress on Monday, the latest fallout from being caught buying cocaine from an undercover federal agent.

Radel went through the traditional motions of a man who was willing to remain in office: going to rehab, doing a few tearful interviews and meeting with top Republicans to discuss his future.

Either those meetings didn't got well, or he is unwilling to suffer through a campaign that would assuredly narrow in on his personal life.

Former Florida state Rep. Paige Kreegel announced a primary campaign to challenge Radel in the first week of January, calling for "serious, sober representation" and a super PAC has already raised more than a million dollars for his campaign. Connie Mack, who held the seat before Radel, is also a possible contender.
