The Environmental Protection Agency’s new rule on carbon pollution is the latest headache for Democrats trying to defend a fragile Senate majority.

Republicans seized on the Obama administration’s call for power plants to cut their carbon emissions 30 percent by 2030 as an opportunity to attack Democrats from energy-producing states — some of the party’s most vulnerable — for what they characterized as the party’s job-killing energy policies and overreach from the president.

Even Republican candidates in states where the proposal is likely to have minimal impact, like Michigan, went on the attack. There, Republican Senate candidate Terri Lynn Land knocked the proposal as an “enormous regulatory attack on coal,” and called on Rep. Gary Peters, the Democratic nominee for Senate, to oppose it.

But Democrats are doing their best to turn the issue into an asset. Kentucky Democratic Senate candidate Alison Lundergan Grimes lambasted the proposal and launched an advertising campaign declaring her opposition to Obama’s policies on coal.

And green groups, a key Democratic constituency and one that could have a pivotal role in this fall’s elections, were elated. League of Conservation Voters President Gene Karpinski lauded the new rule as “the biggest step we’ve ever taken for the biggest challenge we’ve ever faced.”
