Transcript for Election Results 2012: Senate, Congressional Races
about the house and the senate. Republicans are going to stay in control of the house. One of the surprises last night, democrats, firmly in control of the senate. Reporter: Basically, the bottom line here, you have a congress that's more deeply divided than the one we just had. But the senate, this is a story of missed republican misses and losses. In massachusetts, the most closely-watched senate race in the country, elizabeth warren, a big victory over scott brown, the republican. In indiana, a solidly republican seat for 36 years, democratic joe donnelly beats mourdock. Mourdock made the controversial comments about rape and abortion. Going again, missouri, this was the best chance to defeat an incumbent. claire McCaskill, she beats todd akin. Again, controversial comments about rape. Virginia, the testimony, tim kaine beats george allen. And in wisconsin, the first openly-gay member of the senate coming in, tammy baldwin beating tommy thompson. It now looks like in the senate anyway, the democrats will gain as many as two seats. And the only two we're waiting for are montana, where the republicans hope to win, but they are trailing right now, and north dakota, another place. More women in the senate than ever before. Reporter:19 right now. 20 if the democrats win in north dakota. Getting close to the country being reflected. John boehner remains speaker of the house. Jon karl, thanks very much.
