You can't both sides this one. Biden is a massive headass for not stepping down and allowing a Democratic primary, but he didn't abandon rural America. Look at where the majority of the infrastructure money was headed. Remind me again, was it Trump's concepts of a health care plan that was a lifeline for rural hospitals, or was that the ACA?
For all their flaws as a party, Democrats don't generally ignore rural livelihood, and they certainly do a better job of catering to it than Republicans. They're just not as good at paying rural lip service on the places these people get their media. If you thought Democrats actually only cared about they/them, you're not in a position to question how tuned in anyone is to politics. If you're just talking about how rural voters feel about the parties, then sure, but nobody was disagreeing with that, just calling them naive for thinking that way.
