The issue here is that the people that already believe in these sources already think the president is lying. On the other hand, people that think the president is telling the truth aren't going to believe those sources. So what does this do? Are there that many people on the fence? Because everyone I know in the middle already thinks this is laughable (Utah votes by mail and every Republican in CA I know votes from home!), those on the left think it is about voter suppression, and those on the right think it is about voter integrity.
While I don't disagree with the program, I'm also not sure what it solves.
