Progressive-Democrat President Joe Biden has ended his campaign for reelection. Some, notably Republican Vice Presidential candidate JD Vance, have said that if Biden quits his campaign, he also should resign from office.

I tend to agree with that sentiment, but not from the idea that, as Vance has suggested, if Biden is too unhealthy to run for reelection, then he’s too unhealthy to continue in office for the next six months.

My view is that if Biden resigns soon—this week, maybe—that would make his Progressive-Democrat Kamala Harris the new Progressive President. That, in turn, would give Harris a measure of the power and influence of incumbency for her own election campaign. It’s a question, though, whether the scant four months until election day (especially with early voting starting so early in many jurisdictions) would give her that much of a boost.

It’s a question, too, whether any such boost would be mitigated by her already quasi-incumbency as the sitting Vice President. Sitting Vice Presidents do get elected, vis., George Bush the Elder, but not always, see Hubert Humphrey. On the other hand, Presidents campaigning for the first time after “inheriting” the office due to the departure in one form or another of the prior incumbent, typically don’t get elected, from John Tyler forward. Gerald Ford, who had three years of incumbency not a mere three or four months, is the latest example of that difficulty.

But maybe Biden is too selfish and feeling too much betrayed by those syndicate family members he thought he could trust to make the move. Or maybe he’s stubborn enough to stay in office just to show them they can’t, either, run him out of office.
