Rep. C.A. Dutch Ruppersberger (D-Md.), who spent months publicly mulling a run for Maryland governor, was spotted Tuesday night at a fundraiser for gubernatorial hopeful Anthony G. Brown that featured former president Bill Clinton.

So does that mean that Ruppersberger is siding with Brown, the state’s lieutenant governor, in the June 24 Democratic primary?

No. At least, not yet.

In January, when Ruppersberger announced he would seek reelection to the House rather than run for governor, he left open the possibility of making an endorsement in the governor’s race.

Spokeswoman Jaime Lennon said Wednesday morning that Ruppersberger is still mulling his options in a primary that includes Brown, Attorney General Douglas F. Gansler (D) and Del. Heather R. Mizeur (D-Montgomery).

“He has communicated with the attorney general, and he will communicate next with the lieutenant governor about his vision for the state and, in particular, the Baltimore region,” Lennon said. “Then he will decide if he is going to endorse a candidate.”

Ruppersberger, a former Baltimore County executive, said in January that he was urged by many people to run for governor, including some concerned that all the major Democratic candidates are from the Washington region.

Brown’s fundraiser Tuesday night in Potomac attracted more than 700 people and netted more than $1 million for his campaign, according to aides.
