A new advocacy group seeking to expose what it says will be the high cost of climate-change legislation to consumers is spreading its message with the same tools that catapulted President Obama into office: blogs, Twitter and other new media outlets. The Cost of Energy Information Project (CEIP) is the latest addition to the dozens of ad hoc organizations pressing lawmakers on Capitol Hill to consider the bill's effects before casting a vote. This group, backed by energy-producing interests, is clearly in the anti-legislation category. The group plans to reach outside of the Beltway to engage citizens who, organizers insist, have been excluded from the lawmaking process. CEIP was put together with the help of Morris Reid, a Democratic lobbyist, and Republican Gov. Haley Barbour of Mississippi, a former chairman of the Republican National Committee. Mr. Barbour said two other prominent Republican consultants, Ed Gillespie, also a former RNC chairman, and Ed Rogers assisted with the formation of the organization.
