The economy sure, but lets not discount crime and border secuity as massive disappointments under Biden/Harris besides inflation.

It is these things that dems need to attempt to understand rather than just shouting how bad it will be, and doing nothing to explore their positions on such issues.

Perhaps, but I think Democrats already understood those points. They had already pivoted significantly on border security by supporting the bill earlier in the year. Yes, I know none of you think it was enough - but it was further to the right on immigration and border security than they had been in nearly 30 years, so it's a clear sign they understood the electoral damage they were taking on that issue. So too with crime. Harris' return to emphasizing her career as a prosecutor, and the criminal justice activist wing of the party letting her largely make that move unchallenged, is a pretty clear indication that the party realizes how bad "Defund the Police" hurt them.

But they don't seem to have internalized the role inflation and the economy played in their defeat. Democrats seem genuinely puzzled why voters were so unsatisfied with the economy. It's not that hard. Inflation got really bad, for a long time Democrats said it wasn't much of a problem and so there was no need to change the course on their priorities, but voters thought it was very much a problem and so lost confidence in the Democrats to handle the economy. So they turned to the party that was saying, "Yes, this is a problem, and the Democrats ought to be doing something differently to fix it." Because even if the Republicans don't have a great plan to fix the economy, at least they recognized that the economy needed fixing when the Democrats didn't.
