What Trump is doing, you're not seeing, because you are not in a media bubble primarily comprised of one of the following 4 constituencies (all of which represent "secret" upsides where trump can gain new voters outside of what we view as his hard upside limit:
- protestant (evangelical) Hispanics
- disaffected young black men
- disaffected bro culture young (primarily white) men
- Anti-communist hispanics (e.g. Cubans, but many others; here's where the Komrade Kamala attacks and memes are pointed)
He's got someone doing data for him that is very good at identifying these constituencies where he can eke out new votes (and I question how organic that is to his campaign, but that's a different story).
In any event modest gains in those constituencies could swing a close election. Take a moment to be scared, and then go work your ass off to save the country you love. If you've never knocked on doors before it may seem intimating, but if an introvert like me can do it, you can too.
