Prediction: Republicans retain control with 50 seats by virtue of VP Mike Pence's tiebreaking vote.
Result: 53-47 to GOP (32 correct predictions/35 total races called, 1 pending or 91.43%) Synopsis: Although not as successful as my House prediction, this was still a solid prediction. I was under the (somewhat unfounded) belief that the margin in favor of Dems in the House elections would reach a level in which the "macro" effects Nate Silver alluded to in 538 would take over, helping Dems hold more seats. 8% is a pretty solid lead for D's over R's, but not sufficent, hence some misses. Florida again proved a close miss here (same with Governor's race).
