The wild thing is, this map is from Reagan's SECOND election. Guess he must have been doing a pretty good job - Clinton never won a majority of the voters even ONCE.
What's funny is that Reagan could have won Minnesota, but didn't want to campaign seriously there to embarass Mondale totally.
He lost Minnesota by about 3000 votes and could have won it too if he stopped by to campaign, but didn't want to humiliate Mondale.
