Obama Coakley Ad Rolls Out (VIDEO)

With one day left to go before Massachusetts hosts a critical election for a U.S. Senate seat, President Barack Obama has cut a new television ad for Attorney General Martha Coakley.

The spot casts the Democratic candidate in a populist light -- fighter for the working class, foil of big financial interests, and, perhaps most importantly, ally of the president.

"Martha knows the struggles Massachusetts working families face because she has lived those struggles," Obama says in the ad, clipped from video of the president's stump speech on Sunday.

The Democratic Party is clearly doing its best to nationalize this race, with the implicit theory being that the appeal of Obama and his agenda will be enough to drag Coakley over the finish line. The numbers suggest an uphill battle. While Coakley's campaign says their internal numbers have them with a two-point lead, the most recent independent poll released Sunday night has her trailing Republican Scott Brown 51 to 46 percent.
