More like 70~90% of the country, dude.
I frequent New Mexico, Oklahoma, Colorado, Texas, Arkansas, and Arizona for work. I have to talk to hundreds of different people a month. I get paid hourly so I talk a lot before driving another few hundred miles, and not a single person I've met voted for biden.
Note: all the people I talk to have jobs, so that likely has a lot to do with it.

Maybe once a month I'll see a biden bumper-sticker, but I still see about 200 Trump stickers/signs for every one for biden. biden paraphernalia is ONLY found in large liberal cities, like denver, co or las cruces/albuquerque, nm, and drive 2 minutes out of the city to see American and Trump flags on nearly every property.
