Less than three weeks ago our model gave Rossi a 31% chance of victory; today our model assigned a probability of victory of 49.9%. Rossi did briefly surpass the 50% threshold two days ago. This race remains incredibly tight not only in the polls, but in our estimates as well. Our model suggests that Matt Kirk would be the 49th GOP Senator and assigns him a 55% chance of victory -- clearly still in the toss up category.
On the House side, Republicans are in a strong position according to our models. Based on our analysis of InTrade data Republicans now have a nearly 77% chance of winning control of the House of Representatives.
Today our model estimates that Republicans will hold between 228 and 231 seats in the next Congress. This would represent a pickup of between 51 and 54 seats from the 177 they held following the 2008 election.
As noted yesterday, our analysis of InTrade data suggests that Republicans have a roughly 1/3 chance of gaining 60 or more seats.
