This is a pretty decent article by Eli Saslow in the Washington Post that I would recommend everyone read. In any kind of political struggle, you have to be able to put yourself in the mind of your opponents and understand them. You can’t really easily counter your opponents tactics with your own if you don’t understand how they think, and more importantly understand what they are doing wrong. There’s a lot of lessons in here for our side, and the chief lesson is that the tactics you find emotionally satisfying are not always (really not usually) the ones that matter in terms of gaining desired political outcome. Emotional blackmail is similar to open carry in at least one way: it’s a tactic, not a strategy. Waving the bloody shirt will only get you so far.
