Few people remember that Trump likely won the nomination due to "cross-over" voters in states with open primaries. There was an organized effort by Democrats to cross-vote for him as the Republican candidate under the belief that he couldn't possibly defeat Hillary Clinton in the actual election. I don't know if there is a way to determine whether or not that effort actually succeeded, but it did exist and was spoken about with great pride until Trump became the President.
