Baca had already said he would run this election, and had indicated he'd challenge Rep. Gloria Negrete McLeod (D-Calif.), the woman who beat him last campaign. But now he may challenge Rep. Gary Miller (R-Calif.) in a seat that already has a strong Democratic recruit, Redlands Mayor Pete Aguilar (D).

"When I'm ready to tell you, I'll tell you," Baca told the Inland Valley Daily Bulletin when asked about the possibility after, another local Democrat said Baca had told her that was his plan. "Let's just say that I'll get back to you next week on that story."

Miller is a top Democratic target, and won last election largely because of California's unusual primary system, which allows the top two vote-getters to advance to the general election regardless of party. That system and a crowded field left him and another Republican running in the district. 

With more and more Democrats jumping in against Miller it creates the possibility that the scenario could play out once again this election and cost Democrats a shot at one of their best pickup opportunities of the cycle — though that would require another Republican to jump in the race as well.
