1. Credible - yes the fact that he Tweets nonsense all day and night instead of governing the Nation. He continues to spout over and over the same sayings so it will be ingrained into those who are slavish followers. He says: FAKE NEWS, BUILD A WALL, TRADE WAR TARIFFS, IMMIGRANTS ARE TERRORISTS etc. The belief that he is a malicious sociopath is CREDIBLE.
2. The fact that his wife is here legally, the fact that he won the election fairly, the fact that he is not a traitor and in league and being blackmailed BY Putin. The fact that people are still defending him? IN CREDIBLE
3. Anything quoted about him or by him by his sycophantic cabinet and FOX NEWS? UN CREDIBLE. OR LIE. As we like to say. LIE.
