From the NYT of all things.. http://fivethirtyeight.blogs.nytime...n-2014-increasingly-looks-like-a-tossup/?_r=0 A race-by-race analysis of the Senate, in fact, suggests that Republicans might now be close to even-money to win control of the chamber after next year’s elections. Our best guess, after assigning probabilities of the likelihood of a G.O.P. pickup in each state, is that Republicans will end up with somewhere between 50 and 51 Senate seats after 2014, putting them right on the threshold of a majority. The chart below reflects our current overview of the Senate landscape, including the probability estimates. (The estimates are not based strictly on a formula but instead are best guesses, accounting for the partisan lean of each state, the quality of the prospective candidates, and approval-rating or polling data to the extent that it might be informative.) When we last conducted this exercise in February, our projection was for Republicans to win between 49 and 50 Senate seats, meaning that their standing has improved by about one seat since then. It then goes into detail on each stat race..
