I’ve spoken to more than one midwesterner who is dismissive of Jan 6. “Not an insurrection”, “bunch of idiots”, etc. There’s a real disconnect on what Jan 6 actually is.
It’s also clear in those conversations that they don’t see it as Trumps fault.
As such, there will be no perception of Biden as a Democracy custodian. In order for that to happen, perception of Jan 6 would have to undergo a seismic shift 3yrs later.
