Following Massachusettes' Senate special election upset, three electorally-endangered Senate Democrats have already jumped ship on the liberal agenda on Global Warming, supporting legislation to prevent the EPA from regulating carbon-dioxide.

CBS News reports:

Republican Sen. Lisa Murkowski of Alaska is leading the charge to block the Environmental Protection Agency from regulating greenhouse gasses, and today she got some support from across the aisle: Three Democratic senators signed onto Murkowski resolution to bar such regulation ...The Democrats, the Associated Press reports, are Ben Nelson of Nebraska, Mary Landrieu of Louisiana, and Blanche Lincoln of Arkansas.

The AP is so clueless, they use a photograph of nuclear power-plant cooling towers expelling water vapor to illustrate "greenhouse gases". So far, the EPA has not labeled water as a "pollutant".
