If it was a piece of political theatre designed to get the Liberals in a tissy, I’d say the immigration ban been remarkably successful so far.
You only have to look at the choice of the countries involved and what they mean to Trump supporters to guess at why they were chosen (and more importantly why other countries who’s citizens have perpetuated more terrorist acts weren’t) I’d imagine to Mrs and Mrs Trump Voter of Spigot, Idaho, Somalia is where we had a war and kicked ass (Black Hawk Down tells them this is so) They’ve been at war with EyeRacK so banning them makes perfect sense, EyeRan are their implacable foes if they watch any news at all, they’ll know the name, so that makes sense, and if they’ve even heard of the other countries: “Who they hell cares anyway, we shouldn’t jus’ let anyone into our goddam country anyway” and there’s practically nothing those countries can do about it.
That some Judge in Manhattan has stopped it temporarily even plays to Trump’s narrative of the Liberal Elite trying to thwart his “sensible plans”. The Liberals can complain all they like, Farah and MPs even makes it a better story, as it looks “even handed”.
