Unfortunately, Trump supporters only listen to two billionaires (Musk & Murdoch) who are in cahoots with him to fleece the people by lying to them. They are fed a firehose of misinformation daily that tells them Trump is their Messiah who can do no wrong.
If his stance was lower prices yesterday and tarrifs that raise prices today, he is right both times. If he was the peace candidate yesterday and dropping bombs on foreign countries today, he was right both times. If he was the transparent politician who was going to stop corruption and he fires all the inspectors and oversight people and installs people who will prosecute political rivals, he was right either way. He said he would bring economic stability, then he (illegally) cuts federal spending and asks 2M workers to quit with no plan to maintain services of the government, they say he did it!
How do you reason with people who will support whatever stance Trump takes and it changes day to day?
