In other words, you can continue to play the "blame the other guys" game, but the data suggests that while polarization on the right is a more recent phenomenon, the right still hasn't caught up with the level of polarization that exists on the left.

Seems to me that could easily be attributed to the fact that there is a lot more room to move left than right.
