Republicans lie about the things they do and get attention for it because of how they get the message out.
Democrats need to do a better job of promoting the things they do accomplish. Don't need to lie, just do a better job of getting the press to write stories about the positive things they do. They need to call Republicans who have racist policies racist instead of dancing around it. A few are doing it, but are ignored because they aren't party leadership.
Biden needs to call Trump a racist and a fascist on national TV. Get the public motivated! Taking the higher ground doesn't get people motivated, it just means more of the status quo.
