As per usual, low information voters cannot pick up on the subtile chicanery and deceit of the Trump/Vance candidacy. I think most people are honest folk who simply cannot imagine that there are dishonest people in the world who are able to lie continually and/or gaslight with such skillful but guiltless abandon.
A lot of blame lies at the feet of, dare I so rudely say, idiot newscasters who can't even remember that there is no such thing as a "Kamala Harris Administration" (yet), but there was and still is a Biden Administration - of which, she is still a part, but only as a supportive advisor, the traditionally invisible role of any Vice President.
