Watergate x 1000.
Add a bunch more zeros. Watergate was a pimple on a gnats ass compared to this treasonous coup attempt.
We should never allow weak moral and/or political comparisons to Watergate to gain any purchase whatsoever. It should never be forgotten that the attempted deep state overthrow of the legally constituted government elected by the people is the most serious threat posed to liberty since the CWI.
Worse, while it was never illegal for states to form a separate confederation and secede from the union - thereby creating their own, independent government - it has always been illegal to wage war against standing, lawfully constructed government authority through non-democratic means.
This is treason, pure and simple. It's literally the text book definition of waging, aiding & abetting war against the government. The punishment is execution; literally swinging by yardarms on the Mall.
