U.S. Rep. Robert Wexler, D-Boca Raton, will probably back state Sen. Ted Deutch in the special election to fill Wexler’s congressional seat, a knowledgeable Democratic source says.

Wexler himself wasn’t ready to make any endorsements today as he confirmed he’s leaving Congress in the middle of his seventh term to become president of the nonprofit Center for Middle East Peace and Economic Cooperation.

Wexler has a long history of getting involved in Democratic primaries and other local races. His most memorable activity was probably his successful 2004 effort to topple former elections chief Theresa LePore and install Arthur Anderson. Wexler later cooled on Anderson and was neutral when Anderson lost his reelection bid last year to Susan Bucher.

In 2006, Wexler backed Deutch in a Democratic state Senate primary and helped him defeat better-known, better-financed state Rep. Irving Slosberg. At the same time, Wexler was instrumental in Jeremy Ring’s victory over Ben Graber in a Democratic state Senate primary in Broward County. Now Deutch and Ring are among the candidates considering running for Wexler’s congressional seat.

Wexler hinted he’ll make an endorsement soon.

“I have been known to get involved in primaries before, both to people’s happiness and chagrin…I’ve done it before. I care deeply about the person who will replace me and lead this community in Congress, so we’ll leave that for another day,” Wexler said.
