Kanawha County Delegate Suzette Raines announced earlier this year she's running for state Senate, but the freshman Republican is also reportedly thinking about jumping in to the congressional race.
Ron Walters Jr., son of Delegate Ron Walters, R-Kanawha, is also considering mounting a campaign.
State GOP Chairman Conrad Lucas said the crowded field shows interest in the state party is resurging.
"This is a very exciting time to be a Republican in West Virginia," he said in a statement. "The interest in this race shows the strength of our party and the passion Republicans have to fight against Obama's War on Coal and overreaching policies.
"There was a time when getting Republicans to run for office was like pulling teeth. I'm proud to say that in this new era for West Virginia, those times are over."
Last week, political prognosticator Larry Sabato, who analyzes political races for the University of Virginia Center for Politics, changed his view of the race. Citing the current field, Sabato changed his rating of the potential outcome from "likely Republican" to "leans Republican."
"Republicans, meanwhile, don't really have a top-notch candidate; one of the contenders, Alex Mooney, is also a former state party chairman - but in Maryland," wrote Sabato and Kyle Kondik, another analyst.
"This race could edge into toss-up territory soon if a strong Republican does not emerge. . ."
Former state Democratic Party Chairman Nick Casey and Kanawha County Delegate Meshea Poore plan to seek their party's nod for the race. In July, Casey announced his campaign had raised more than $450,000. Casey contributed $300,000, according to federal campaign filings.
