Rep. Ami Bera, Sacramento Sheriff Scott Jones Advance In Congress Race

SACRAMENTO (CBS13) — Democratic U.S. Rep. Ami Bera and Republican Sacramento County Sheriff Scott Jones will square off in one of the nation's most closely divided congressional districts.

Bera and Jones were the only two candidates in the 7th Congressional District, which includes the suburbs south and east of Sacramento. They both advanced by default Tuesday, with initial returns showing Bera leading by five points.

Bera has been under siege from the left since he supported giving President Barack Obama "fast-track" authority to negotiate a trade deal last year. The move infuriated the labor unions that helped Bera eke out wins against Republicans in 2012 and 2014.

Jones is running on immigration and national security issues. He rose through the ranks of the Sacramento County Sheriff's Department and was elected sheriff in 2010.
