Is Brown tied with Coakley in Mass.?

Two new polls tell very different stories about the race to fill Ted Kennedy's Senate seat.

A new Boston Globe poll gives Massachusetts Attorney General Martha Coakley (D) some breathing room in her. Coakley has a 15% lead over Republican Scott Brown in the survey.

But on the other hand, a poll released by Public Policy Polling (PPP) shows the candidates in a statistical tie, with Brown garnering 48% to Coakley's 47%.

The conflicting numbers won't ease the worries of Democrats. If they lose the seat, it would cost them their 60 seat supermajority and possibly complicate their plans to pass healthcare, depending on when Brown would be sworn in.

Democrats played up that risk yesterday in fundraising email to supporters.

"You need to know this: Polls are tightening in Massachusetts, and America's future hangs on getting Martha Coakley elected to Ted Kennedy's seat on Jan. 19," the DSCC wrote in an email.
