If Thursday's ruling by the Maryland Board of Elections on which gubernatorial campaigns are allowed to raise money during the upcoming General Assembly session proves anything, it's just how arbitrary Maryland's campaign finance laws are. The board's decision, which can and probably will be appealed in court, held that Lt. Gov. Anthony G. Brown can't raise money for his gubernatorial campaign during the session because he is a state-level official, but his running mate, Howard County Executive Ken Ulman, can. Likewise, Harford County Executive David Craig can raise money for his gubernatorial bid, but his running mate, Del. Jeannie Haddaway-Riccio, cannot.
