Its also counter-optics to ensure that optics for election fraud won't prevail.

Let me explain. For the Dems to be able to pull off another fraud, in addition to actual fraud mechanics (mailin ballots, hammer and scorecad etc), they also need optics to explain Biden's win.

In 2020 the optics was literally "People voted for Biden because it was simply a vote against Trump"

In 2024, that optics won't work because Biden has been so thoroughly discredited, even by MSM. So the optics will be focused purely on the battlegrounds.

By putting Vance in charge of this, you can counter the optics by showing how he is changing the minds of fence sitters (which I expect we will see plenty of in the coming months as Vance gets to work)

In addition, since Vance was once an extreme Trump hater, he can relate to people with TDS and give counter arguments.

This is as much a information warfare as anything else.
