“who are the rest of those voters”
I have observed the emergence of a new ‘class’ in our society. I haven’t coined a name for them yet, but something like ‘transitional poor’.
Some of these people have jobs, but many in their extended families and circle of friends don’t - they are either on welfare or some sort of fake SSA disability. A common factor in this class is drug abuse. And many of society’s most basic requirements seem to be insurmountable hurdles for them. It may start with a DUI...followed by a conviction for driving on a suspended license and a few days in jail...they might have trouble getting their kids to school on time, and get a visit from child services. And of course, their lives are a constant sprint away from bill collectors. Whatever the reason, somewhere along the way, they have a ‘bad encounter’ with law enforcement, the courts, or some other symbol of authority.
And, they can’t accept that any of this is their fault...so they ‘hate cops’...say f#@% the judge...screw the banks...etc.
Once they hit that point, getting them to vote democrat is as easy as dangling something ‘free’ in front of their noses.
My observation is that the primary cause for being ‘transitional poor’ is drugs.
I understand the difficulty in naming them; I suspect “new socialist” is the closest I can come (and it is an imperfect oversimplification). They are pessimistic about their economic futures (living paycheck to paycheck, if they even have steady work), and assume they’ll be using the safety net at various times. Also, there is no game plan for retirement; it simply isn’t in the cards.
FWIW, I thought Trump won many of those types; they are tired of this “global economy” impact on the lives they once knew, and feel completely marginalized.
