As he ponders a 2016 presidential bid, Maryland Gov. Martin O’Malley (D) is continuing to raise money for his political action committee, including at an event in Baltimore County next week featuring music by folk rocker Stephen Stills.

Stills, best known for his work with the band Crosby, Stills & Nash, is scheduled to play Thursday night in the backyard of longtime O’Malley booster Martin G. Knott Jr., a Baltimore area businessman. Tickets to the event start at $1,000.

O’Malley used his PAC to try to help other Democratic candidates on the ballot this year, traveling to campaign with them, donating money and dispatching and paying for 32 campaign staffers to work in Maryland and battleground states.

The fresh fundraising by O’Malley’s PAC signals that he is going to try to stay visible in coming months as he decides whether to move forward with a White House bid that would likely pit him against Hillary Rodham Clinton for the Democratic nomination.

“His PAC will continue operating as it has been, working to promote progressive candidates and issues,” O’Malley spokeswoman Lis Smith said Thursday night.

Some have argued that O’Malley’s ambitions were dealt a blow last week with the decisive defeat of his hand-picked successor in Maryland, Lt. Gov. Anthony G. Brown (D), by Republican businessman Larry Hogan.

In recent days, O’Malley’s PAC has been aggressively promoting the event with Stills, with one e-mail urging his close Baltimore supporters to help build the audience to show O’Malley they still have his back.

“The most important thing that you can do is to be there for the Governor,” the e-mail said. “Whatever you can give to the PAC is much appreciated, but more importantly it is critical that the Governor looks around and sees his friends in the room that night.”

In another e-mail to supporters, O’Malley himself wrote that he wants “to bring my longtime friends together for a night of music and fun . . . one last time while I am governor.”

“Let’s remember the good times and look ahead towards the future,” O’Malley wrote.

O’Malley, who fronts a semi-retired Celtic rock band, is expected to take the stage at the event as well.

Stills, who has penned such hits as “Love the One You’re With” and “Southern Cross,” has been a long-time friend and supporter of O’Malley. He is now 69.

In 2006, when O’Malley was running for governor for the first time, Stills appeared at a fundraiser on his behalf in Chevy Chase. In 2010, when O’Malley sought re-election, Stills played another event, this one at Knott’s Baltimore area home.
