At The Hill Jeff Greenfield does his level best to explain the balloting rules of the Democratic National Convention and how, although unless he withdraws President Biden is likely to be renominated, almost anything can happen:
Particularly in an open convention, some early procedural votes could make all the difference. They could pave the way for Vice President Kamala Harris to quickly seize the nomination, for instance, or allow for a broader, more competitive contest. But either way, the rules will matter. (In what follows, I have drawn deeply from the wisdom of Josh Putnam, whose FHQ site is absolutely required reading).
The TL;DR version is it’s complicated.
At present I hold two seemingly contradictory opinions. First, I think it is very likely that President Biden will not withdraw, resign, or otherwise voluntarily remove himself from the 2024 election. Second, I think the optimum outcome for the Democratic Party would be if he did.
Clearly would have been better if he had withdrawn a year ago. It’s a toss up on whether it would be better now in terms of winning the election.
