What constitutes a landslide victory?

McGovern is still alive.

I agree, I think that the definition of landslide should be based on both the popular and electoral vote. A minimum of 55% of the popular vote should be a basic requirement, along with 75% of the Electoral. Thus I would say that Eisenhower's victories should both count, but not Reagan in 1980.

Reagan in 1980 I would not consider a landslide since he only got 51% of the popular vote. Good point too, MiamiU, that Wilson in 1912 was landslide in the Electoral vote but far short of even a majority in the popular. That definitely wasn't a landslide victory either.
You yourself said that a landslide should be a minimum 60% of the popular vote, Christopher. I don't feel the threshold should be that high since that would even elminate Reagan in 1984.
Obviously what constitutes a landslide is purely objective on the part of each individual. I think we can all agree though that it should not be so broad as to include lots of elections. It should be reserved for only those in which there is a clear sweeping mandate across the entire population for one candidate.
