I love political cartoons for their ability to sum up so much using so few words.
Major hat tip to Varangianguard, who directed me to this very recent Matt Bors comic:

This is what I've been on about lately! The hypocrisy of both Left and Right is absolutely on parade these days, as each winks at their own side's transgressions, while jumping up and down about the other side. Here's an idea: hold your own side to the fire. You might get something done!
Or, for a lack of cognitive dissonance, just back the Libertarians who are always pro-civil liberties.
