In the debate last night, he used the word "bigly" (as in the adjective of big). In complaining about stop-and-frisk being ruled unconstitutional, he said the decision was made by a "very against police judge".
When the DNC hack by his friends in Russia (which he amazingly tried to deny on their behalf) was discussed, he said it could have been done "by a 400 pound fat man" and not the Russians.
When asked about his use of planned bankruptcy and phoenixing of companies (using the fact that companies have limited liability to buy services, property etc on account, then transfer those assets to a new company and allow the company that bought them to go into liquidation... in other words, not paying all the people who provided services to it.... it's not that much different from mafia bust outs where they do that to small companies they take over). And Trump then bragged about it! He said "I take advantage of the laws of this country, that makes me smart".
The strangest line of the night was when he was attacking Clinton on foreign policy (about which he clearly has absolutely no idea), he bizarrely said "No wonder you've been fighting ISIS all your adult life". Wait, wut? No wonder you've been fighting ISIS all your adult life? Hillary Clinton was born in 1947. She became a full adult in American terms in 1968. The ISIS/Sunni uprising occurred in 2013.
All he could talk about was "I'm extremely strong. I'm so vigorous. I will be an extremely strong leader, I can do deals with Chaina. Crooked Hillary is weak, bring back the jobs and make America great again".
I usually hate the tendency to ascribe stupidity or maliciousness to one's political enemies. I always say that it is perfectly valid for someone to look at the same set of facts and come to a different conclusion. Not this time. If you support Trump, you're a nihilistic moron.
