Trump is in a fade. Republicans need to unite behind a strong alternative candidate. Florida governor Ron DeSantis is the leading aspirant, but DeSantis is a terrible human being. His latest moral crime — an attempt to attract conspiracy theorists and crazed MAGA cult voters generally — is to demand a grand jury investigation of “criminal or wrongful activity in Florida” involving the “development, promotion and distribution of coronavirus vaccines,” even though the striking success of vaccines in reducing severe illness and deaths is a matter of public record. The best candidate Republicans could put up would be Liz Cheney. Unfortunately, they have in effect expelled her from the Party.
