I'm sure most liberals want to prevent another DJT from coming to existence and so cheer what came out via the Veritas leaks.
But if the democrats win in 2020 it will mean that major billion dollar corporations used AI to influence the perceptions of people to produce a political outcome they were looking for. And that is way scarier than any theorized Russian meddling.
They don't care. LIberals, the left, etc can't think that far ahead. It's all always about how they feel right then and there.
