The National Republican Senatorial Committee will turn the screws on vulnerable Democrats on Tuesday with automated calls on the EPA's newly proposed carbon emissions limits hitting voice mail boxes in Virginia, Louisiana, Colorado and Alaska, all states where incumbent Democratic senators are seeking re-election.

The committee will target Northern Virginia swing voters and Gulf Coast residents specifically, and independents in Colorado and Alaska more broadly, a committee spokeswoman said.

The regulations are “all part of [Obama’s] radical energy plan, which he said would make electricity rates ‘skyrocket,’” the robocall in Virginia will say. “Tell Mark Warner higher gas prices and new EPA regulations just don’t make sense for Virginia.”

The proposed rule, which will be finalized a year from now after public comment, would cut carbon dioxide emissions from existing coal plants by up to 30 percent by 2030 compared with 2005 levels. The full story is here.
