Ben Highton gives “the Republicans a better than 99 percent chance of continuing to control the House after the 2014 elections”:
In fact in our 1,000 simulations of party control this week, the Republicans won a majority of the 435 seats in every single one. … Even for those interested in specific House elections, there is not a lot of uncertainty. By our estimates, in 408 of the 435 House elections, one party is favored to win with chances that exceed 90 percent. The Republicans have better than a 90 percent chance of winning in 231 races and the Democrats have a better than 90 percent chance of winning in 177. The overall lack of competitiveness is striking, if not entirely surprising.
