Yea, sure. Trump has a lot of negatives, but being "the lowest IQ person ever to be elected president" isn't one of them.
For example during his speech last night, at one point he said,
"If you agree with this statement, then stand up and show your support: The first duty of the American government is to protect American citizens, not illegal aliens..."
That was brilliant. Not a single Democrat rose. It was a perfect dilemma question. It put the Democrats in a bind. Stand and applaud with Trump or sit and show America you don't give a shit about American citizens. Democrats chose to sit. They hate Trump that much. That isn't "low IQ," it's political savvy and brilliant.
Of course, the Democrats likely won't pay much of a price for that as their base hates Trump equally, so they don't care about anything else.
