Enviro group buys ads backing Coakley in Mass. Senate race

“On Tuesday, we can say yes to clean energy jobs and greater energy independence by electing Martha Coakley as our new senator,” it states. The ads began airing Thursday and will run on Boston-area broadcast and cable channels until the Jan. 19 special election, according to LCV.

Brown has attacked the climate bill during the campaign, calling cap-and-trade a “giant new tax on energy.”

Recent polls in the race between Brown and Coakley, the state’s attorney general, have been conflicting — one poll released this week showed Coakley with a comfortable lead, while another showed a dead heat.
