Yes, Nixon ran a terrible and unappealing campaign which was bailed out by fundamentals. He was leading in an enormous landslide over the summer and into early fall, and Humphrey ultimately recovered to within an inch of victory. Most likely Humphrey would've won had the campaign gone on for 1-2 more weeks.
I can't tell whether that's ironic. LOL
It's not. He took one of the best climates for the Republican Party in the 20th century and came within a centimeter of pissing it away. Our national recollection of Nixon as some kind of Machiavellian genius is completely undeserved; he was a bad politician and an
unbelievably bad tactician.
