Crossroads GPS at first painted Elizabeth Warren as an "Occupy" sympathizer...

But now it says she's "too cozy" with the big banks...

The high-profile Massachusetts Senate race is already getting a significant TV ad buy. The environmental group, the League of Conservation Voters, is going up with a $1.8 million broadcast and cable ad buy in the Boston media market, according to a source with the group.

The ad accuses incumbent Republican Sen. Scott Brown of having "gone Washington" and that he "hasn’t voted a single time for the environment since he’s been in Washington, which is something we’re pretty sure his constituents are going to be surprised to hear," the source said.

Senate candidate Elizabeth Warren (D-MA) raised $3.15 million from 11,000 donors with 96% of contributions being $100 or less, her campaign said in a press release today.

Warren, who hopes to win a Democratic primary and challenge incumbent Sen. Scott Brown, got into the race less than a month ago on Sept. 14th.

Official numbers for all candidates are expected on the Federal Election Commission's website Saturday.

The Boston Globe’s top story: “House lawmakers voted overwhelmingly last night to strip police officers, teachers, and other municipal employees of most of their rights to bargain over health care, saying the change would save millions of dollars for financially strapped cities and towns. The 111-to-42 vote followed tougher measures to broadly eliminate collective bargaining rights for public employees in Ohio, Wisconsin, and other states. But unlike those efforts, the push in Massachusetts was led by Democrats who have traditionally stood with labor to oppose any reduction in workers’ rights.”
