Yes, U.S. Senator Joe Manchin (Demublican-WV) is a repugnant reptile who richly deserves your contempt. His vapid, fascism-enabling opposition to ending the Senate filibuster and to passing the We the People Act (H.R.1) is despicable.
The filibuster, which requires 60 of 100 Senate votes to hear and pass a bill, is an arch-reactionary practice long used to block elementary civil rights, labor, and other reforms. As long as it holds, Congress is a big sadistic game of right-wing Simon Says.
You can forget about seeing the passage of serious and substantive liberal and progressive reforms, no matter how much support such reforms have from, well, we the people. The re-legalization of union organizing (as in the House-passed Protect the Right to Organize Act)? Serious gun control measures to block the insane, escalating epidemic of firearms violence and mass shootings? Substantive police reform to end the continuing epidemic of racist police brutality?
You can forget about all that and more as long as the neofascist white nationalist party of Trump, January 6, and the Big Lie has the power to invoke the filibuster and say “no, sorry, we no like, that’s communism.”
