Former West Virginia Gov. Gaston Caperton indicated Monday that he would not run for Senate next year in an interview with the local radio outlet MetroNews.

“I think I had a great eight years as governor, and I think that’s probably where my political career began and will probably end,” the 72-year-old Democrat said. Caperton served as governor from 1989 to 1997.

The list of candidates interested has been steadily expanding since Democratic Sen. Jay Rockefeller announced his retirement on Jan. 11. Republican Rep. Shelley Moore Capito announced her campaign for the seat in late November.

Among the well-known Democrats mulling the race are former Sen. Carte P. Goodwin, Secretary of State Natalie Tennant, state Supreme Court Justice Robin Davis and former state Democratic Party Chairman Mike Callaghan.
