In 2002 he won his current seat in the state Senate, representing Cabell County and parts of Wayne County.
Rahall was first elected to Congress in 1976. In a Monday article on the political website Politico.com, Rahall said he expected Jenkins to switch parties and try to run for the seat. In 2010, former Democrat state Supreme Court Justice Elliot "Spike" Maynard flipped to the GOP in an unsuccessful bid against Rahall.
"I'm not going to run away from those that brought me to the dance and renounce my party because I disagree with our president," Rahall told Politico. "But I've dealt with traitors before, and I'll deal with traitors again."
Jenkins said he's been outspoken in his recent criticism of Washington politics. He opposes the Affordable Care Act and believes Obama and the federal Environmental Protection Agency are waging a "war on coal."
Jenkins donated $500 to Rahall's campaign in 2010. Monday Jenkins said he did not contribute in 2012, which reflects his current view of Rahall's performance. Rahall's campaign also donated $1,000 to Jenkins in 2010.
A campaign spokesman did not return a call for comment Monday, but the following statement was sent on Rahall's behalf Wednesday morning:
"Flip-flop. How many times is Evan Jenkins going to switch parties? Not for public service, but for self service. Clearly, this time his new found Republican bosses in Washington have promised him the world. Yet his promises to West Virginians now ring as hollow as his word."
