Not surprised in the least about Manchin. He would not get elected dog catcher in West Virginia if he impeached Trump. Not sure what Sinema's reasons are, but coming from Arizona, no mystery there either really.
The Democrat Party is transitioning ot the Communist Party of America, and people best wake up from their slumber. Idiots like AOC and her band of anarchists that pal around with her should literally be silenced, unless the party wants to suffer dramatic loses in November, 2020.
Time for Pelosi to go, and she better go now versus allowing AOC and Co to take over the House.
