This is a case of terrible citation sinking what might be an interesting article.

Where did those exit poll numbers come from? Were there other exit polls that didn’t support the thesis?

Who knows, because the author doesn’t cite except to the general cites. Not a supportable analysis, and quoting RFK Jr. is not the same as quoting an “expert.” He’s gone done the conspiracy hole a lot, and he’s a bit of a loonie.
