you have a number of races tight here. tommy thompson could pull out a win. nebraska, north dakota and montana. you have three races in traditionally blue states, besides missouri which is claire mccaskill. she is expected to win in that state. at least right now. but the polls are tight. missouri and pennsylvania, what of those? pennsylvania is the story of the night. romney wins and pennsylvania goes to tom smith against bob casey. then look what you have. 50 to 50 in the u.s. senate. if it s a president elect romney, lit be a vice president it will be vice president elect ryan. that is the tie-breaking vote in senate.
