What's funny is that Reagan could have won Minnesota, but didn't want to campaign seriously there to embarass Mondale totally.
In consolation, Mondale did get 85.4% of the vote in DC.
That's right. His campaign people calculated that he was so close in Minnesota that all it would take is one or two quick visits by him there to win that state too. The aides were giddy at the thought of a clean 50-state sweep - an absolutely unprecedented scenario in modern times (not seen since the earliest days of the republic). But he overrode them and refused to go there, because he didn't want to completely humiliate Mondale. That's the kind of human being he was.
Ahh ..... I still fondly remember flipping the TV channels that night, cycling between Gunga Dan and the others. I just couldn't get enough of watching their long faces as they tried hard not to cry. That was always my favorite part of election nights back then.
