Most Trump supporters wouldn't know what a teleprompter was if it looked them in the face. Kind of like common decency and general directions.
Simple ones that have been around for years like, 'wash your hands before returning to work'. You don't have to do what any sign tells you dammit, they were printed by those commie pinkos....
Plus they can't read a fucking word it says or involve any critical thinking even if they could.
Trump has teleprompter at every speech and they are as visible as the day is long. He's going to be fucked in the debate.
