Manchin sucked but there was a lot that got done under Biden that wouldn’t have if you replaced Manchin with a Republican, which is exactly what woudlve happened if they went after him (and is what happened what he retired). Manchin voted with the Dems far more often than he didn’t.In other words Manchin was considered “good enough” by the democrats. Hell Biden even gave Sienema compliments as she destroyed his legacy.
