So if you break it down (based on the last I looked at it, Pew Research iirc):

• Urban counties are twice as likely to be Democratic
• Suburban had leaned Republican for years, but suburbs have been leaning Democrat for a bit under a decade.
• Rural (on the same timeframe as the suburbs) has been going more Republican, though just a bit less in the ratio as Urban.

The most Trump support is in rural, where more than half support him fully (so full maga territory). Republicans there are more likely to be full maga than in suburbs or urban areas, where republican maga support drops by about 10%.

Democrats in the same areas are fairly equal across the board in their lack of support for trump, about a 50% greater dislike by Democrats in those areas then liked by Republicans.

The urban, suburban, rural breakdown is very accurate as a representation of maga enthusiasm.

EDIT: I though it important to mention too that Republicans in rural areas have an age split as well. Gen X-ish and up is where the support for Trump is, about 50% more than the millennial and under Republicans.

This is oversimplifying the problem. Democrats from urban areas have failed for decades to adequately address the needs and concerns of rural voters. When one party ignores you (and often speaks of you with open contempt), it's a no-brainer that you would be inclined to vote for the party that caters to your concerns. The Democrats handed rural voters to Trump on a golden platter.
