Democrats claim that Adolf Hitler is the most successful politician in American history, having been elected president in 1968, 1972, 1980, 1984, 1988, 2000, 2004, and 2016. "Hitler" is, of course, Democrats' favorite smear against every elected Republican president since Richard Nixon. It's their default position, their go-to slander, because it's a wonderfully efficient word. "Hitler" is Lucifer, Beelzebub, and the boogeyman all rolled into one. "Hitler" encompasses terror, torture, racism, and every other "ism" an ambitious demagogue could imagine. "Hitler" says it all.
