See here. In the country of Gambia, the president was voted out, but has declared a state of emergency so the new president won’t get to take power. (If he were allowed to take power, it would be tomorrow.) Notice that there are leftists suggesting that Obama declare martial law. I don’t think that will happen simply because I don’t think Obama can count on either the police or the military to do his bidding in such a situation (plus his opponents have more guns than his allies do). However, I assume there will be nuts who will try to assassinate him (see here). I remember hearing all the talk about how right-wing nuts were going to assassinate Obama, and it never happened.
Which just goes to show that leftists are not especially reality-based.
