ignore them. Let the Republicans take them on, since most of them are voting against their own interests anyway. Focus on minorities/suburban voters, that's what got the House in 2018.
Just stop. I could write a whole essay about why, in my case, I am voting very much
in my own economic interest (I'm white and I live in a ruralish/exurbanish area that's hard to definitively classify as rural or not-rural) by voting straight ticket R at every election, but I know I'm not going to convince a literal 15 year old whose entire shtick is "LOL dumb racist hicks".
To address the topic, Dems don't need to win rural whites outright to win elections. They just need to avoid losing them by Saddam margins. It would be insane to expect Dems to win rural whites outright, because like blacks with Dems, the interests of rural whites very clearly lie with Republicans. Thus Dem outreach to rural whites is kind of like GOP outreach to blacks - it's about narrowing the margin of defeat - but much more fruitful because rural whites are a MUCH more elastic demographic than blacks. Losing rural whites 75-25 instead of 90-10 would improve Dem margins by 5-6 points in many states. Like many people have pointed out in this thread, local candidates de-emphasizing or taking a different approach than national DNC talking points on fossil fuels and guns would be a big step in the right direction for them.
