Aside from the terminally online politicians (like Mike Lee, AOC, Cruz, MTG) most do not use their own accounts or even look at them. They might have a firm that measure constituent engagement, but still to this day the most effective way to complain to your congress person is a phone call or email. If we're being serious, the latter is what these bot farms, etc are after. They want to influence actual constituents to do their ultimate bidding. Now if we can get evidence of a huge phone campaign using AI voice, that would be much more alarming. Israel is doing it, and Iran/Russia/Hamas adjacent are doing it. There's absolutely no denying it.
