SAN DIEGO (FOX 5/KUSI) — It was up to the voters to choose who will represent San Diego County in the U.S. House of Representatives for the next two years. On Election Day, San Diegans cast their ballots for the next representative of each of the county's five congressional districts — District 48, District 49, District 50, District 51, and District 52. Each race is critical to determine the balance of power in Congress for the next few years, although one contest in particular, District 49, has been a notable target for Republicans.

Mike Levin, emerged as one of the more competitive congressional races in California, with millions being funneled into the race by both sides as they hope to grab the majority in the lower congressional chamber. The polls closed at 8 p.m. Tuesday and results will be released in batches until a winner is called. Election officials say the results released immediately after the polls closed largely account for ballots cast prior to Monday, Nov. 4 through early voting opportunities.
