All the lying on its own by itself tells you there's something seriously wrong with Trump. (Now at least 20,055 false claims in 1,267 days, as of July 9, 2020 -- an average of almost 16 per day.) Now we can't believe a single thing Trump says, which is a real shame for a President of the United States.
Of course there's clearly much more wrong with Trump, and even his defenders know he's an asshole. His niece, trained in psychology, wrote a whole book about it. Look at the country now compared to what it was four years ago -- it's seriously damaged politically, economically, in public health, in public trust, in racial justice, in economic equality, in peaceful streets. Trump is the difference, and his incompetence, especially with respect to the pandemic, is the difference. His racism and arrogance and incompetence are the difference, not Democratic mayors, who were there before Trump but without all the protesting and rioting.
Anyway, The Daily Howler is worth reading, in my opinion too.
