I think Democrats at the national level underestimate how much inner-city Democratic mayors, city councils, school boards, and district attorneys determine their image as a party. If suburban swing voters, when commuting into the city center to work, shop, go to a show, etc. see homeless encampments and vacant storefronts, it's going to hit the Democrats' image as a party that can run things. Republicans in city government tend not to be in big cities, they are more often in suburbs and small towns, which don't have the same kind of homeless problem, and thus don't have the same kinds of challenges projecting an image of being a safe, lawful community.

I'm sure it's a solvable problem for Democrats, but first they have to resolve to address it, rather than just wishing that voters didn't feel this way.
