Democratic leaders have stood by the president as he faces questions about his ability to defeat Trump in November. But privately, many are expressing concern.
Moreover, according to a senior Democratic official, the party leadership would have much more control over choosing a replacement if Biden were to drop out after receiving the nomination than if he did so beforehand. Once a candidate is officially nominated, there is a process for the Democratic National Committee members to choose a successor. Biden is the dominant force at the DNC, and his preference for a successor would surely carry sway.
If Biden were to exit before that, his delegates might do what he asked of them — but they wouldn’t be bound in the same way they are now. In that scenario, the delegates could nominate anyone, and there could be a political brawl at the convention.
I'm really torn on this because his debate performance really was shocking to me. But the incumbency is a point in his favor which is lost if he's replaced. I'm going to stick with him but if something disruptive happens like a legitimate border crisis or the economy suddenly tanks - THAT'S when it would be imperative that he be replaced. If one or two of his other favorables disappear then the incumbency will start to become a noose.
You just described replacing him at this point. I don't think he should have been running in the first place but the primaries are already done and he won.
