Yes, hard to believe, but it's true. Trump on Fox and Friends, April 2018:

“Remember, we won the election. And we won it easily. You know, a lot of people say ‘Oh, it was close.’ And by the way, they also like to always talk about Electoral College. Well, it’s an election based on the Electoral College. I would rather have a popular election, but it’s a totally different campaign,” “It’s as though you're running — if you're a runner, you're practicing for the 100-yard dash as opposed to the 1-mile.”

“The Electoral College is different. I would rather have the popular vote because it's, to me, it's much easier to win the popular vote,” he continued.
