House Majority Leader Eric Cantor lost his Republican primary today in a completely befuddling upset that no one saw coming. When people saw that Cantor was behind David Brat, an unknown and underfunded economics professor, in the returns, jaws dropped, and dropped, and dropped until they hit the floor and left everyone so speechless they had no worries of needing to express their shock in more than 140 characters. As was very evident from how Twitter responded.

There was the realization.

There were the "holy crap" tweets.

There was glee — from the left and the right.

There were jokes.

And then finally, there was much analysis.
