On Tuesday, Democrats took control of the House and the Senate. As of this writing, they won 29 House seats (with a handful still in the balance), slightly below the post-1930 average for the six-year itch in a two-term presidency. They took the Senate by the thinnest of margins — a one-vote majority, delivered to them by a margin of 7,188 votes in Virginia and 2,847 in Montana.
Decades ago, this size of a shift wouldn't be as meaningful, that's true. But in our gerry-mandered age, when re-districting has virtually assured parties of winning certain districts every election, this is an enormous landslide. That's why Krauthammer has to reach back to 1930 to make his point. This wasn't a squeaker, this was a loud and clear rebuke.
