Real Clear Politics is showing CA-20 to be a Democrat hold tonight. The Hill says incumbent Democrat Jim Costa had picked up 3000 votes in the interim since the election, even though as of November 9 the totals showed Costa had trailed the Republican challenger Vidak by 27 votes. Vidak apparently had not yet conceded.
RCP also shows NY-25 to be a GOP pick up over incumbent Democrat Maffei, an Obama freshman, who conceded to the Republican challenger Buerkle after Buerkle's tally was trimmed only by roughly a hundred votes from the 659 vote lead she had as of November 10.
So the net Republican gain now stands at 63 with two races still not called: NY-1 and CA-11.
