It could.
It might.
But even if that's a component of their position, I suspect it may have as much or more to do with the president's age than the vice presidential attributes you've mentioned.
I blame Biden as much as Harris for this. CERTAINLY the VP's obligations are Constitutionally enumerated. BUT ! The VP's role in any presidential administration is determined by the president.
In any administration, but particularly in the presidential administration of the oldest man ever holding the office, succession is an issue, more so in a 2nd Biden term, and more critically important with Russia at war.
So I ask you S2 #200, when was the most recent time you read a report of VP Harris in the news? Doing something constructive? Demonstrating impressive executive skill? Not that Biden's much different from previous presidents in this regard, but Biden's kept Harris substantially out of public view. And if Biden tried to recover from this now by launching an unannounced campaign to address that, I believe it could be recognized as such, simply supplying political ammunition to Biden's partisan critics.
Candidly I don't know whether Harris would be a capable, perhaps even wise U.S. president. But I recall enough of her campaign for the presidency to confess she left me unimpressed.
Replacing Harris for the 2024 race is no panacea. For obvious example, replace her with whom? Defense Secretary Lloyd Austin might deserve consideration. Secretary Buttigieg is one of the most nimble-minded Democrats I can name. But Norfolk Southern has left egg on his face.
Bottom line: If Biden doesn't change running mates, perhaps Biden can at least change Harris' image, nurture public confidence in Harris as a capable, resourceful, competent exec. Unfortunately that's a task that may beyond both Biden & Harris combined.
