Additionally, politcal attacks like this are fun. Jump on someone before they get a chance to denounce something they obviously were going to announce and them when they do denounce it you can claim it was only because of your pressure... or even better hopefully by the time they denounce it everyone has long stopped caring about the story and people think they never did denounce the actions of some really extreme group that may have even had no connection to a party or movement.
I can imagine that presidential assassains went undenounced, not because the opposing party was happy, but because it was common sense that politicians were against violence.
As for the actual threats by politicians when they call people "Dead men" they mean in the next election, how goofy would you need to be to think otherwise?
