The status quo (money stream) for all “professional” politicians was threatened by Trump, and he had to be eliminated by any means necessary. They, the political establishment of both parties, were obviously at their wits end because of his popularity and felt pushed to the extreme of fraudulently electing joe. Unfortunately for the establishment, the fraud necessary to achieve their desired result was so blatant it’s now the “turd in the punch bowl” which is getting harder and harder to cover up.
