How do Iowa Democrats rebuild/retool?

[TML]

As far back as 2018, it was mentioned in a political blog about Iowa politics that mid-size cities appear to be a bigger problem for Democrats than rural areas. Specifically, the report focused on the following counties (and the corresponding mid-size cities they contain):

Clinton (Clinton)
Cerro Gordo (Mason City)
Muscatine (Muscatine)
Marshall (Marshalltown)
Des Moines (Burlington)
Jasper (Newton)
Webster (Fort Dodge)
Wapello (Ottumwa)
Lee (Keokuk)
Marion (Pella/Knoxville)
Boone (Boone)
Mahaska (Oskaloosa)
Carroll (Carroll)
Buena Vista (Storm Lake)
Jefferson (Fairfield)
Dickinson (Spirit Lake)
Clay (Spencer)

Before 2016, Democrats used to routinely win these counties collectively, but Republicans have won them collectively in pretty much every statewide race since 2016, and they've even picked off state legislative seats based in these areas. Democrats need to stem their losses in these places if they hope to win statewide again and/or make up ground in the state legislature (it is not possible for Democrats to come anywhere near a majority in either state legislative chamber if they don't regain previously lost seats in these areas).

Move to South Dakota.  Like, every Democrat in Iowa move to South Dakota to try to turn it blue.

That would be a terrible thing for South Dakota if it ever happened.

Eh?

This individual has a pro-R bias and thus views any pro-D trend negatively.
