Here's a measure of how much of a landslide you had. Add together your 270 EV (or whatever is required to win) best states. What is the minimum percentage of the vote, or margin of victory in them?
Reagan 1984
He got 59.23% or more in 270 EV worth of states, with a margin of at least 18.99%
Johnson 1964
He got 62.09% or more in 270 EV worth of states, with a margin of at least 24.59%
Johnson had a much better landslide, despite the fact that he lost a lot more states.
It's like in American Football just because one team got the most yardage doesn't mean they scored as many points as another team who didn't get as much yardage..
Exactly. I read about a game between Alabama (ROLL TIDE!) and Texas A&M where A&M dominated all the statistics, but Alabama won the game thanks to special teams and some defensive plays. The A&M domination meant nothing in the end.
It doesn't matter how many popular votes you get, the EC is the only thing that matters.
Personally I would say a landslide would be a 300+ electoral vote win.
