I actually deleted a call-out to you and wrote that you'd say something similar (I think what I wrote was that your position is the party would re-orient itself around the candidate and not the other way around).
Unfortunately, quoting my own post...
This is the part I wanted to write more because it seems overlooked from the left-leaning media and it's something I'd raise with Kendall Scudder if ever got face time with him.
Pundits keep complaining about the relative lack of a lefty media ecosystem comparable to what's been touted on the right (e.g., Klein wondering why there isn't a lefty Charlie Kirk going to Liberty University and debating students on secular versus religious government efficacy at delivering happiness to citizens). I also don't see anyone talking about a strategy to crack the information bubble that a lot of Trump voters put themselves in.
The relatively low hanging fruit tactic is having Dem communicators that are able to talk about more than politics in an interesting way and have them guest on podcasts that aren't already full of other Dems (i.e., if it's had Chris Murphy on in the last three months then it needs to be speaking to a broader audience).
I'll use two terrible examples because neither are Americans--Melissa Barrera and Dua Lipa are pretty smart, media savvy, and unlike Michael Jordan, willing to make political statements on issues that aren't obviously popular. I'm sure someone who knows celebrities better can suggest someone besides McConaughey or one of the boomers. Most of these younger voters that Harris lost are the kind that listen to Rogan and "came for the jokes, stayed for the anti-vax talk".
The thing that Klein points out repeatedly (and we've debated here) is that these voters aren't "deplorables" who are "irredeemable" (quoting HRC) unless you want them to be, and the party is losing elections because it's made too many voters feel unwelcome.
