Yeah, sorry, not buying it. The media has been trying the same tactic for a year now and all it's done is make Trump even more popular. A number of people are flocking to Trump because, according them, he's 'keeping it real and calling it like he sees it.'
I'm going to disagree. It made a certain group of authoritarian whites flock to Trump but almost everyone outside that group hates him. The Authoritarian Whites make up about 40% of the republican party, which was enough to give him the primary thanks to winner take all states and a divided field, but he's very unpopular with the country overall. If there had only been one establishment candidate after Iowa instead of three, he would probably have beaten Trump since early on the combined votes for Jeb, Rubio and Kasich were actually ahead of Trump. And everybody who isn't a republican hates him, he's the most unpopular party nominee by a wide margin. So I think this kind of ad is pretty effective. Most Americans don't want a man like Trump in the white house, so pointing this stuff out will do a good job getting liberals and moderates to vote Clinton and non-authoritarian republicans to stay home or vote libertarian.
