I see: so while Nixon is fighting a full-up war 10,000 miles away, an all-consuming Cold War at its height and simultaneously dealing with a very large and pervasive campaign by the Left's home support of the enemy camouflaged as a "peace" movement with full support of the media - he's "paranoid" ?
I'd say he had his hands full with actual enemies, not invented ones.
His paranoia was that he had that election so in the bag there was no good reason for the shenanigans to go on that resulted in his pending impeachment.
He beat McGovern like a rented mule.
