They had two outstanding candidate (for Democrats anyway) and they turned their backs on them. So they left and are now part of Trump's cabinet. Tulsi Gabbard and RFK Jr.
I think they keep looking for the worst possible candidates, the ones who will fully commit to the WEF, UN, China and/or Soros. They want a candidate who refuses to serve the American people and who support and defend the Constitution. The more they refuse the more they want them.
