Thirteen true-or-false questions make up Lichtman’s “Keys to the White House,” which he claims provides a clear indicator of the candidate who will be declared the winner on the autumn ballot.

Every question concerns one of the two rival nominees; if the answer is “true,” the contestant gets a “key,” and if the answer is “false,” the other contestant wins the point. The candidate of one party is expected to win if they receive six or more keys.
