(CNN) - Incumbent Democratic Rep. Jim Costa has won his bid for a fourth term representing California's 20th Congressional District, according to updated vote totals released Wednesday by the California Secretary of State.
Costa defeated Republican candidate and farmer Andy Vidak.
The win for Democrats holds Republicans to a net gain of 63 seats, with two House races still undecided - California's 11th and New York's 1st Congressional Districts.
The Democratic incumbents currently lead in the vote count for both contests, although neither GOP challenger has conceded.

I really thought the repugs was going to win all the remaining seats. They have control of the house any ways. I wonder what is going to happens when they take over the house next year. I can see the Dow falling and the world economy taking a nose dive.
