The phrase I remember was Dick Nixon before he dicks you.
Without a doubt I felt satisfaction when Tricky Dick resigned, but I understand why your father found it depressing that a president of the United States would engage in such deceitful illegal condut. Shouldn't integrity and honor be an absolute requirement for the highest office in our land?
Which brings us to the case of Donald Trump. That such an egregiously unfit creature could be elected president in the first place is depressing, appalling, and alarming.
His crimes and brazen hubris are unsurprising, but as much as I have long despised the Republican Party it breaks my heart that it and roughly 40% of my fellow citizens have morphed into a cult worshipping at the feet of a malignant narcissist whose incessant lies are obvious to any person capable of critical thought.
Our Constitutional democracy is in an existential crisis, with no end in sight.
