Since the outcome of the election was not what the left wanted, something must have gone wrong. This cannot happen. And whatever it might have been that caused insolent Americans to not vote as the left wished, this horrid thing must be found, must be isolated and must be killed.
Of course, another approach would be, say, next time nominate a better candidate, offer better ideas and do a better job of persuading people to vote for you? Nah! Ban something! That's the left's response to losing because every leftist knows that if things had been fair, right and just, they would have won.
