> First, tell me the numbers for electoral votes. I would consider that a landslide

Then you don't understand what a landslide, electoral or otherwise, is. Of the post-WWII elections, virtually all were bigger wins, electorally, the exception being both of George W. Bush's elections, Nixon's 1968 election, and Kennedy's 1960 election.

Actually, while WWII is often used as a breakpoint for considering modern elections, the same is true if you extend the timeframe to post-WWI.
