My thing on this for ACORN and all sorts of lefties who cry foul over right-wing tactics is simple. If you really believe that you're facing a vile enemy armed with an array of dirty tricks, the correct action is not to be institutionally sloppy and then decry the deep evil of your opponents. You knew that going in. The correct response is to run your ship that much tighter.Hey, Tea Party types, and conservatives in general: the same goes for you. No, you're not all the kind of people who would throw slurs at John Lewis...so stop allowing signs and posters at your events that make you look like a group that would be fine with that. Stop using language that stops oh so carefully short of inciting people to violence. Run a tighter ship.
This advice is unlikely to be heeded on the left or the right.
