But words have meaning, and calling this "open support" is flat lying. He's unbelievably terrible at the job of president and human being: you don't need to lie in order to make the case that he is.
Just because your bubble (and my own) consists entirely of people who are aware of how terrible he is doesn't mean everyone is, and lying for political reasons is exactly the kind of thing that makes big chunks of the country inhabit alternate realities where all news is fake and the notion of a fact disappears from political discourse. You should be ashamed of yourself.
