Cover art for The Love Of Richard Nixon lyrics by Manic Street Preachers

i dont think this one is sarcastic, i think its saying that nixon did do some good things, he was a human after all. everything we hear today in connection of nixon is bad (watergate etc), but theres more to it than that. challenging the conventional wisdom maybe. maybe its the republicans who betrayed him, maybe the historians for the way his memory has been regarded.
