I have read the gamut of treatises on politics and economics -- books on libertarianism, Marx, Adam Smith -- you name it. I concluded that ideologies are like toolboxes; that no single book contains the entirety of the Truth; that common-sense is the main imperative and blind adherence to an ideology departs from common-sense as a lazy man's solution to thinking and reading.
In my callow youth after college, I had some very simplistic ideas about these political choices, and actually chose the GOP, thinking that they championed "free market competition." Then I discovered that the GOP was less interested in "perfect competition," drew its biggest supporters from concentrated industries, and had been co-opted by Big Oil, possibly Big Defense and interests that lean against the public well-being.
After that, I was watching the campaigns and elected officials over the past two decades, verifying the Liars and the Lies through my own investigation. Around 2004, I changed my voter registration to "Democrat," because there were no other feasible choices for my alignment which had any chance of winning major elections.
And I've long since come to realize that one very often doesn't have a smorgasbord of choice about anything. If a Dirty Asshole-Sandwich ran against Trump, I'd merely swallow my frustration and vote for the Dirty Asshole Sandwich.
I have realistic expectations, you see . . .
