What gains has Biden made outside of his base?

Since 2020, what gains among voting blocs has Biden made?

He thought he had the youth vote in the bag with student debt relief - but then came October 7th. All that good will was flushed down the toilet.

What incentive has he given other groups (other than not being named Donald Trump) to actually get out to vote for him in November? I mean people that weren't already voting for him - what gains has he made in the past 4 years?

I feel like he's relying on the 2020 strategy at least in part of of mail in ballots, but how many people are going to be doing that again without Covid and the fear of Covid being an actual motivating factor?

None, and he's lost some of his own base. They probably won't vote for Trump, but it doesn't take that many withholding their vote to cost him the election.

I can actually see a scenario where 18-24 year old Muslim youth actually vote for Trump as a middle finger, while their parents stay home or vote green or other.
