I mean there is a conversation to be had that it would be different. The debate performance would normally shift votes, but didn't. The assassination attempt would normally shift votes "hugely" but it hasn't shown. I think people knew who they were going to vote for before we knew the nominees. No new information was going to change that.
I would just argue that with everything being "unprecedented" we shouldn't rely solely on old election data. Trump won in 2016 because he ran a different campaign, yet Democrats still seem to want to run old style campaigns.
