I Am Interested In Politics

Trump said the sound wind turbines make (he mistakingly called them windmills) causes cancer. I know we're all supposed to be used to him saying stupid nonsense by now but this just seems more crazier than his usual claims.
I remember his lawsuits over wind turbines in Scotland which could be seen from his golf course and how he lost the suit but to then come up with the claim the noise they make cause cancer seems like a very delusional way to get revenge.
If he either really believes this his mental state is worse than I thought or if people believe him after he said it I worry there truly is nothing he can say that people won't believe.
