Jon Lieber, head of Eurasia Group's coverage of political and policy developments in Washington, DC shares his perspective on the US midterm elections.

So last night the US had their midterm elections, and the theme of the night is that Republicans underperformed, given the fundamentals of the race. Democrats had a pretty good night overall with Senate candidates outperforming their polling in Pennsylvania and New Hampshire. And as of today, the results in both the Senate and the House are probably too close to call. The environment generally favors Republicans overall, and so they're likely to pick up a majority in the House, but that majority is going to be much smaller than most pundits were expecting as of yesterday before votes started to count.
