President Obama is set to campaign for Mass. Attorney General Martha Coakley to replace the late Ted Kennedy and keep control of the Senate. “President Obama, who had no plans to travel to Massachusetts, may be heading there to campaign for a Democrat caught in a surprisingly tough race for a Senate seat that is crucial to Democratic hopes of keeping control in the Senate. Quoting Democratic Party sources, the Associated Press says Obama will visit Massachusetts before Tuesday’s special election in which state Sen. Scott Brown is running well, and in at least one poll, is beating the Democrat, Atty. Gen. Martha Coakley. There was no immediate comment from the White House. Earlier this week, White House spokesman Robert Gibbs said there were no plans for Obama to campaign in person for Coakley, though the president has campaigned electronically. But that was before the latest polls showing Brown running very strongly. Brown has pledged to be the 41st vote against heathcare overhaul, enough to defeat Obama’s main domestic priority.”
