The AP reports:
U.S. Sen. Jay Rockefeller, who came to West Virginia as a young man from one of the world's richest families to work on antipoverty programs and remained in the state to build a political legacy, announced Friday he will not seek a sixth term.
The 75-year-old Democrat's decision, coming at a time when his popularity in a conservative state had been waning for sparring with the powerful mining industry and supporting President Barack Obama, told The Associated Press ahead of his formal announcement that it was time to retire.
After about three decades in elective office, it was time to "bring more balance to my life after a career that has been so obsessively dominated by politics and public policy and campaigns," he said. "I've gotten way out of whack in terms of the time I should spend with my wife and my children and my grandchildren."
