This happens a lot more frequently than you might think, and on both sides. Just a month ago, for example, in late August I worked on a job for a D.C.-area production company, FP1 (fp1.com), on a
conservative political ad consisting of "testimonials" bashing Kamala Harris and Josh Stein, and it featured
paid actors reading scripted lines from -- you guessed it -- a teleprompter. It was every bit as counterfeit as the one you're sharing above.
Side note: Yes, it's true, I will work on jobs that in principle I disagree with. The entire crew was guilty of this. In fact, without the liberal film industry, Donald Trump and Republicans would have to hire people off the street to produce their commercials. What can we say other than we're whores for money. But hey, it was an amusing and almost enjoyable day on the job, especially since everyone there knows that Kamala Harris will be our next president and Josh Stein will be our next governor. No harm, no foul, right?
