To me, this is just what he says about everything.
All of his opponents are terrible and have a disastrous record.
He's great and has done brilliant things and he will save everyone from disaster.
It has no connection to reality, except that gullible people believe him. But he only promises things to take advantage of the fools who fall for the nonsense.
Anyone whom knows anything sees the truth, which is that he lies and cheats all the time, and has accomplished nothing.
