As far as I can tell, MAGA folk don't exactly object to democracy.

They just agree with mr Trump that our democracy should not be poisoned by people whose bloodline goes back to Asia, Africa, or South America.

America should be controlled by real America. Those whose ancestors came from Europe, as mr Trump explained at CPAC in 2013.
