You're looking at a more "global" scenario, and that's 100% valid, because that's where the big bucks are.
But Trump regularly sends out "guilt trip" emails to the MAGAts, begging for money.
You and I might think "If he just got a million bucks from someone, why would he care about $5 from a MAGAt," but I'm sure you remember this one...every penny matters to him, and pissed off MAGAts don't donate.

The Trump Files: The Easiest 13 Cents He Ever Made

In its short-lived existence, Spy magazine had a lot of fun with Donald Trump. The New York-based monthly is best known for making fun of the size of Trumps fingers, but its deepest cut may have come as part of a 1990 prank.
Spy correspondent Julius Lowenthal wanted to know just how cheap some of the citys richest figures were. So he set up a company, called the National Refund Clearinghouse, and sent letters with checks for $1.11 enclosed, for services that you were overcharged for. The letters went out to 58 well-known, well-heeled Americans, 26 of whom promptly cashed them. Curious as to how low they might go, Lowenthal sent those 26 nabobs a second refund check, for $0.64. This time, 13 people cashed them.
Finally, he sent those 13 respondents a check for $0.13. This time, only two people cashed the check. One was an arms dealer. The other was Donald Trump, whom the magazine identified as a demibillionaire casino operator and adulturer.
