was to stand for "Taxed Enough Already" and was a clearly defined idea movement around basic libertarian principles. It was basically like any wing of any party at the time. That wing also had significant overlap with period Dems on things like policing, civil liberties (on which, I'd argue Dems have become more like NeoCons of that era), drug enforcement, etc.

Then the word/phrase got coopted by what became the Trumpist movement.
