Thats true. Nixon made mistakes and shouldnt have tried to cover up for the idiots who pulled that stunt. But the left had been gunning for him since Day 1.
And yes, there were damned RINOs back then as well, who were anti-Nixonians. They and the lefties NEVER stopped harassing him and doing EVERYTHING they could ( including trying to make Ike ditch him, as his running mate for Ike's second term ! ) to trash/get rid of him.
The idiotic beginnings of that failed impeachment took just about THREE decades.
What did poor Mr. Nixon in, was that damned tapping...which every single president, from FDR down, had engaged in!
