Agnew was convicted of TAX EVASION and ACCEPTING BRIBES. Not perjury.
Sorry.
The details hardly matter. What was the last time a prominent democrat was removed from office? Don’t get lost in the forest looking at trees.
And by the way Nixon hardly resigned out of his own volition. He was confronted by prominent republicans by telling him he would be impeached if he did not resign.
Again, name me one president, VP, Attorney General, Secretary of Defense, Secretary of Treasury, Secretary of State or even a US Senatoe belonging to the democrat party was removed from office since I immigrated here 53 years ago.
