The Republic our founders gave us died quite a long time ago and the empire that replaced it is now on it's last legs as well!
Well, as a physician I would say, at the very least, that our Republic definitely seemed to acquire an insidious, fatal disease decades ago and that the Republic seems to be closing in on death very quickly indeed right now. I mark the date of the acquisition of the sickness unto death as the day of the passage (?) of the Constitutional Amendment that made the progressive income tax possible.
With Cruz, we had a pretty good chance of abolishing the IRS once and for all. That chance seems to have died.
(One of the Progressivist co-morbidities sealing our doom was the 17th Amendment, of course.)
