In one recent poll, 36 percent of all voters (and 77 percent of Trump voters) say that the 2020 presidential election was stolen, even though there is zero evidence that any ballot fraud occurred. Such widespread looniness — which is promoted by the president himself — is dangerous. On Oct. 19, a former Houston police captain working as a private investigator for a right-wing group rammed a truck and stuck a gun to the driver’s head because he was convinced the truck was transporting fraudulent mail-in ballots. It was actually carrying air-conditioner repair equipment.
