148. Electoral Vote Landslides Since 1952
They show that candidates who appeal most to their base, tend to lose the election in a landslide.
These elections since 1952 had the greatest landslides, favoring one party over the other(s). Notice that in every case the losing candidate(s) were viewed by a significant proportion of the voters as “extreme”. The Democrats were far to the left, and the Republicans were far to the right. This only tells us that enthusiasm for a candidate who appeals a lot to the base is fun, but historically does NOT get elected. The 2008 election is interesting in that both candidates were viewed by a lot of the voters as extreme. It’s also the least dramatic landslide of the bunch.
I have not found any official definition of “landslide”. One website suggested that 70% of the electoral vote would be a landslide. In 2008, Obama’s victory was 67.8%. In 1968, Humphrey got only 35.6% of the electoral votes, making it pretty close to a landslide against him, assuming that Nixon would have gotten nearly all of Wallace’s votes, had he not run. That also shows that third party candidates do have the potential to influence an election.
