Democrats can’t have black republicans speaking off the plantation.. sad
What are being removed is proveable liars and their lies. If you're going to tweet political disinformation and proveable propaganda on your Twitter feed, you're not going to have a Twitter feed. Everyone is allowed a different opinion, but you're not allowed to promulgate "alternative facts", which in the real world, are called "lies".
Republicans can't run on a platform of "We're going to cut taxes and crash the economy - again", so they make shit up. Although this year, they didn't even bother with a platform, so no promises made, no promises to keep.
When you can't run on your record, and you don't have any plans for the country, or at least none of them that would earn you votes if you published them, and you go whole hog for disease, debt and death, and then try to gaslight the American people into believing that none of this mess is YOUR fault, and the other guy will make things worse, you're on fairly shaky ground to begin with.
