You again? Please stop with the Trump apologism already, we have a trade war that was mostly conducted via twitter, people heard via twitter that their services were no longer required, the whole Mexican affair was conducted via the phone and when that didn't work out led to a slew of angry tweets. There is
definitely precedent enough that if Trump's twitter account would speak the right magic words that you can expect a reaction.
"Dear Twitter Followers, It is with grave heart that I have to ask you to do the right thing for your country, go out and do something about - insert bogeyman of the hour here - and I will be sure to reward you greatly. The time has come to do your part. I personally promise to pardon anybody that ends up on the wrong side of what today still is the law. Let's take this country and make it even greater."
That's just a two minute sample, give me an hour or so and I'll come up with something much worse than that. These things are easier to start than to stop.
