(CNN) - President Barack Obama's making a personal pitch for fellow Democrat Martha Coakley in next Tuesday's Senate election in Massachusetts.
The president is putting out e-mail and Web video in support of Coakley, the Massachusetts attorney general, who's running in the special election to serve the final three years of the late Sen. Ted Kennedy's term. The e-mail and video will be sent out Thursday to the Massachusetts distribution list of Organizing for America, the president's political arm at the Democratic National Committee.
"I am supporting Martha Coakley. As your attorney general, she's taken on Wall Street schemes, insurance company abuses, and big polluters," Obama says in the e-mail. "She'll be your voice, and my ally. And she needs your help."
At stake is the Democrats supermajority in the Senate. If Republican state Sen. Scott Brown wins, the Democrats lose their 60 seat filibuster-proof coalition in the chamber, threatening their chances of passing the health care reform bill Obama hopes to sign into law.
A non-partisan poll released this past weekend by The Boston Globe indicated that Coakley held a 15-point advantage over Brown, but other surveys, including several partisan polls, have suggested the race is much closer.
Brown is hoping to become the first Massachusetts Republican to win a U.S. Senate seat since 1972. Independent Joseph Kennedy, a third party candidate who is not related to the late senator, is also in the race.
