The field of potential challengers to freshman Rep. Ami Bera, D-Elk Grove, continues to grow, with former U.S. Senate candidate Elizabeth Emken filing a statement of candidacy.
Emken unsuccessfully took on incumbent Democratic Sen. Dianne Feinstein in 2012, losing by a wide margin.
The Republican's statement of candidacy, filed with the Federal Election Commission last week, lists Bera's seat in California's 7th Congressional District.
While Emken has not formally launched her candidacy, spokesman Mark Standriff said, "She's in it."
Former Rep. Doug Ose, who left the House in 2005 and is considered a top GOP contender for Bera's seat, said he is still mulling a possible run. Emken contacted him to seek an endorsement, which he declined, he said.
