I’ve spent the last several months trying to settle on a straightforward explanation for why Joe Manchin decided to attack, denude and ultimately destroy the centerpiece of President Biden’s domestic agenda on the cusp of what already looks to be a brutal midterm season for the Democrats.

Manchin loves his coal, sure, so the clean energy provisions at the core of the Build Back Better Act (BBB) were poison to his own personal fortune. He’s a Democrat from a bright red state, and so must cleave at least somewhat to the economic fictions that sustain the right. Given the large chunk of hell he’s carved out for himself, however, these hardly seem like enough to justify the mayhem he has unleashed within his own party.

…and then it hit me in the middle of the night like an arcing splash of ice water dropped on my bed. I sat bolt upright in the gibbering dark and announced to the startled cat coiled at my feet: “My God! He’s running for president!”

Put yourself in Manchin’s shoes. Your own seat is secure until 2024, so there is no need to run for anything next year. Over the long process of murdering the BBB Act, you raked in millions in campaign “donations” from the energy lobby and other right-leaning interests, which means you’re flush enough to fund a national campaign.
