You are right, and I think the important thing to note is that the campaign is not oblivious. They are not and never really were getting too far ahead of themselves with the media momentum narratives etc. Even with record money hauls and donations, they were always always stressing a tight race that will need on the ground grassroots focus. Especially battleground states.
They have never stopped stressing that they were the underdogs and never taking it for granted that there is A LOT of work to do and any way you go about it there has to be record turnout and continued pressure to reach every voter.
If we were seeing the campaign take anything for granted or get too far ahead of themselves cheering on momentum I would be worried more. But everything including the avalanche of campaign and Pac mailers are clearly stressing the challenges and need to volunteer, register to vote, get everyone you know to register and have a voting plan.

Keep fighting the good fight for people that absolutely despise your existence.
Ultimately, I think she's facing a number of lingering challenges that if left unresolved, will thwart any further momentum she is going to need to win.
Is she running as an incumbent (inclusive of embracing the Biden/Harris agenda of the past 4 years) or is she running as an outsider who is willing to distance herself from the very administration she has worked for over the past 4 years ?
What are her actual comprehensive policy positions across the board and is she willing to do more press to articulate and defend them ? We are less than a week from early voting ballots being sent out in PA, so anyone running for President should have a clear and concise policy agenda available if they expect to get votes (simply not being Trump isn't enough).
