To pass health care, Democrats desperately need to keep Ted Kennedy's Senate seat in Massachusetts, but the race is extremely tight. To tip the scales in favor of Democratic candidate Martha Coakley against Republican Scott Brown, President Obama wheeled out a Web video and a robocall to voters this week. He will visit the state on Sunday. What are the risks of this last-ditch intervention?

  • Could Mobilize the GOP, says Reid Wilson at Hotline. After explaining that the stakes leave little alternative, Wilson explains the donwside of visiting: "The intensity of voters who view [Obama] unfavorably, or who disapprove of his job performance, is so high that an appearance with Coakley could bring out more GOPers ready to vote for Brown than it could Dems set on their nominee"
  • Risks Obama's Credibility, write Ben Smith and Josh Kraushaar at Politico. The two reporters argue, in Politico's typically dramatic horse-race style, that stepping in is "a risky bet that puts Obama’s own credibility on the line on behalf of a weak candidate in hopes of averting a loss that would shatter the party’s 60-seat Senate supermajority."
  • But on the Balance, Less of a Risk Than Not Going, writes Allahpundit in a post at Hot Air. The conservative blogger is more upbeat about Obama's ability to swing the race. He lays out the alternative scenarios: "If he’d decided not to go up there, it could have been taken as an admission that he’s become ballot-box poison, which only weakens his grip on panicky centrist Dems in Congress. If he does go and she wins, he’s the savior; if he goes and she loses, he looks bad but can claim — entirely credibly — that she was an awful candidate who ran an irredeemably awful campaign ... I think he’ll win her more votes than he’ll lose."
