Rural voters, who the OP asked about, are not the core of the racist rot in the country. That would be the bougie white suburbs, who are also the GOP's core base. Rural voters can be won over by offering them economic incentives via an actual modern welfare state and jobs guarantee.
In essence, offer something concrete to rural voters rather than the usual Dem condescension and half measures, and they will stick to that like white on rice.
The problem is, jobs that is possible to create would not be available in rural areas.
