I was responding the effort to paint the two sides as equal.

The cycle-of-reprisals is a separate point. In a two-party system, transfer of power means change. The minority party will always paint that as reprisal, so if you judge by who-complains-the-loudest, they will look the same. The churn of claims and counter-claims by politicians in the media has become a game with very predictable behaviors.

But if you look at actions, IMO they behave very differently.
