I read this recently:
And it was worth it for the drunk Nixon stories, apparently the guy was a major lightweight.
Notable events Buchanan relates from the 1968 campaign:
-Drunk Nixon walking out into the middle of Fifth Avenue to hail Buchanan a cab and nearly getting hit.
-Drunk Nixon sending Buchanan and other staffer into an airport to get snacks, then as they're coming back Nixon is wandering towards them down the corridor because he decided he wanted some chili. When they get to Miami at 2AM they have to go find an all-night chili place.
-Hunter S. Thompson travels with them for a bit, first he nearly kills them all by smoking next to where the plane was being refueled. Then when he gets his "exclusive hour" with Nixon they spend the entire time talking about football.
-Hunter showed up to the first date Buchanan had with his wife, which was at a hotel with some other politicos/reporters in a group setting. Hunter brought a half gallon of Wild Turkey, which he and Buchanan then consumed entirely while arguing about the Soviet Union to the point of screaming at each other into the morning. The two remained friends until Thompsons death.
It also details Nixon's 1968 strategy of "don't fuck up, let everyone else fuck up, then do something just good enough to look awesome by comparison" and his complete lack of political and ideological principles.
