From The Washington Post:
"On the eve of Election Day, conservative commentator Ann Coulter
suggested that if only people with four U.S.-born grandparents voted,
Donald Trump would win by 'a 50-state landslide.' "
The story notes that if Coulter's standard were applied, Donald Trump, whom she supports, would be unable to vote.
