They have found a smug lie that they can use as an excuse to vote for the bigotry that exists on their side of whatever wedge issue drives their entire identity. Or it is latent racism they don’t want to consciously admit to. Probably both.

Nothing you say or do will get them to admit Repubs are campaigning on a platform of bigotry. “Southern Strategy” “Nuh-uh.” “Goldwater literally campaigned on voting against civil rights.” “Nuh-uh.” “Why are all the Confederate and Nazi flags welcome at Repub events?” “Nuh-uh.” “Donald called all Mexicans rapists and thieves.” “That’s about the economy.”
