U.S. Rep. Shelley Moore Capito has a challenger in this year's West Virginia's Republican primary.
Delegate Jonathan Miller of Berkeley County filed Tuesday to run in the 2nd Congressional District.
Capito has not yet filed for a seventh term with West Virginia officials. But her federal campaign reported a $1 million balance at the end of September.
Miller raised $8,800 by that time. The 27-year-old created his federal campaign in May.
West Virginia's recently redrawn congressional districts remain the subject of a federal court challenge. But the U.S. Supreme Court has allowed this year's elections to rely on the new redistricting map.
Republican Mike Teets also filed Tuesday, for state agriculture commissioner. The lifelong Hardy County farmer came close in 2008, winning 47 percent of the vote for that office.
