I guess he doesn’t really want to win. The first time he ran he didn’t expect to win and that gave him a freedom and a freshness that candidates for president rarely have. This time, he could win and he seems intent on throwing victory away.
I take it from the extremely biased article that he did not say, “poisoning the blood” but rather “poisoned mental institutions and prisons all over the world.” That is a specific statement and has nothing to do with the race hatred of Hitler's intention; but rather the illegal behaviors of invading entrants that undermine society and the rule of law.
