As for Trump's lies, he lies, or has incorrect facts, when it's simply not needed. I view it as a character flaw, everything about Trump has to be "perfect", including his Presidency. And yes, I know politicians lie, but many of them are a bit more clever about it.
But I'm obviously not a Trump fan, at all. He's the only person who could motivate me to vote for Biden (presuming I bother to vote).
