Halvorson closing -- he's now down by just 137 votes (out of 50,617 counted so far) with 52% reporting.
Very amusingly in the Pennsylvania Democratic Senate primary, a fourth candidate called Joseph Vodvarka is on 7%, and was in double-digits in the early returns. Clearly Pennsylvania Democrats were not thrilled with their choices.
Vodvarka is some random teabagger that likes to run as a Democrat for some reason. He got nearly 20% against Casey in 2012, probably from people who were protest voting for Casey being too centrist. One of my liberal friends said he voted for him, then felt dumb when I told him he was a teabagger.
