There has been a fair amount of snickering over Melania Trump’s comment that her husband is “not Hitler.” Yes, that’s a low bar; yes, it usually goes without saying that one’s spouse has cleared it. But remember: She was asked about the claim that her husband is Hitler. Maybe she should have been clever enough to avoid repeating the accusation in her own comment, or just said that the accusation is ridiculous and offensive. In that case, nobody would have made fun of her comment.
