I wouldn't expect them to know. Like Trump, none of these people probably actually read the bible.
Someone will tell them a bunch of nonsense like the Pence Card, and instead of questioning the logic of such a power like no one ever using it before or even double checking it, they will instead just hardcore believe that Pence could just reject 6 states electors and hand Trump the election. They claim to believe in the constitution but know nothing about it, they claim to be Christian while mocking Christ by replacing him with Trump.
