Other than the wealthy and super-wealthy ones the only conclusion I can come to is that Trumpers are either mentally deficient or mentally ill. I've got one of those, of the latter case, in my extended family who believes she was hired by Trump as an "investigator" to look into QAnon kiddie pedi ring stuff. Claims she is even being paid to. Really sad, but everything is about belief.
And when you suspend belief in government, science and reality itself annnything is possible.
