CHARLESTON, W.Va. - After nearly three decades in the U.S. Senate, Democrat Jay Rockefeller of West Virginia said Friday he was ready to retire, calling his unrelenting fight to protect the nation's coal miners one of his proudest achievements.
But in the waning days of his political career, the industry has grown hostile, with coal companies and their conservative allies accusing the five-term senator of being out of touch for defending clean-air regulations and other policies they claim imperil the future of mining.
Rockefeller was also lambasted for support of President Barack Obama's health care overhaul as the president became ever more unpopular in West Virginia.
Rockefeller's retirement puts the seat held by Democrats since 1958 in jeopardy for the party, and well-liked Republican U.S. Rep. Shelley Moore Capito has already vowed to run in 2014.
Though her prospects are uncertain, Capito won a seventh term last fall with about 70 percent of her district's vote, and the state is growing slightly more Republican: The GOP picked up 11 seats last fall in the state Legislature, and two of the three U.S. House seats are now held by Republicans.
At 75, Rockefeller said he wanted to focus on his family and called his decision entirely personal.
"Public service demands and very much deserves nothing less than every single thing that you have to bring to bear," Rockefeller said. "And that's what I have given it. I've been driven to make life better for people here. That's not a slogan for me. It's the truth. And an obsession."
The peak of his career, he said, may have come in 1992, when he threatened to keep the Senate in session over Christmas break if they didn't pass legislation preserving retirement benefits for miners and their families. It passed, he said, and a nationwide strike was averted.
