In 1992, after Pat Buchanan gave one of the keynotes at the Republican convention, it was joked that the recordings of the convention were OK but they'd be much better if you could find them in the original German.
I don't think, this year, it's going to matter. Last week, Trump tweeted this image that could have as easily come from Stormfront or, in its day, Der Stürmer. This is not just another manifestation of the vast left-wing media conspiracy to make Donald Trump look like a bigot. Which, by the way, may be working so well, that reality has overtaken fantasy.
Fake it until you make it, I guess. Well done, Donald.
