Coal-state Democratic candidates are lashing out at President Obama for new Environmental Protection Agency emissions standards that would squeeze the coal industry.

West Virginia Secretary of State Natalie Tennant and Kentucky Secretary of State Alison Lundergan Grimes, both Democrats running for Senate in their respective states, issued stern statements slamming the president for allowing the EPA standards, which would restrict emissions on future power plants, to go forward.

“Yet again, President Obama has taken direct aim at West Virginia’s coal industry. This proposed regulation would effectively prohibit the construction of any new coal-fired plants. This regulation is bad for West Virginia coal miners, their families and communities across the coal fields,” Tennant said in a release.

She added that she's "not afraid to take on leaders in my own party to protect West Virginia's coal industry."

Lundergan Grimes said she was "disappointed" at the ruling.

"After calling on the President to do the right thing, I am deeply disappointed in today’s EPA ruling. Yet again President Obama's administration has taken direct aim at Kentucky jobs," she said.

In the same statement, however, Lundergan Grimes sought to lay the blame on incumbent Sen.

Opponents say the new rules amount to a de facto ban on new coal plants, as the technology needed to comply with the standards isn't commercially available. The EPA and climate advocates disagree, and argue coal is on the decline largely because of decreased demand rather than government regulations.

But the Obama administration's climate policy could become problematic for the two candidates, both of whom are running in states where coal production plays a central role in the economy.

Republicans have been working all week to tie both candidates to Obama's policies, which they say amount to a "war on coal."

"It is plainly evident that electing Alison Lundergan Grimes would ensure that a sworn enemy of coal sets the agenda instead of a Kentuckian. And it will come as even less of a surprise when Grimes continues to loyally support the Obama administration who plans to impose a radical new EPA proposal," reads the release targeting Lundergan Grimes.

Republicans argue that she's beholden to Reid and other Democratic leaders, and her association with him will make it impossible for her to stand up to her party on issues like Obama's climate policy.

McConnell spent much of the week focused on the EPA standards, calling them the latest “administration salvo in its never ending war on coal" in a floor speech during which he called for a vote on a bill he introduced to prevent the rules from taking effect. Reid blocked the bill but acknowledged coal's importance to Kentucky.
