Nate Silver: An Anticlimactic Election So Far

On a national level, it's been an anticlimactic election day so far, uber-analyist Nate Silver of The New York Times says:

Although relatively few toss-up races have been called in the House, Republicans hold leads in most of them, and our model now expects them to somewhat overperform its expectations going into the evening. It's now forecasting a 60-seat gain for them, and has Democrats with just a 5 percent chance of holding the House. Frankly, this night is looking slightly anticlimactic, with both the House and the Senate having moved in relatively clear directions so far.
