These people don't like to work much do they. Schumer is a dolt, but Manchin must have laughed out loud if Biden actually tried to say something coherent and lucid. Sheesh. Biden couldn't negotiate an ice cream cone, mush less a complicated bill.
There was no negotiation. If I were to set the scene ... there was a lot of smiling and handshaking (no masks), “how are you doing ... how are the wife and kids.” Followed by what can we (bribe) add to the legislation or anyone of your family need “some help” (getting in college, being appointed to something with big$$ but not have to show up), followed by pleading ... followed by threats.
Something is keeping the snake Manchin from going forward. Perhaps he fears what the WV mountain people might do to him and others close to him compared to blowhard putz Schumer.
