In the description, you should specify "Major" in this case to mean "Had an active campaign during the primaries". Because there IS a difference (e.g. Scott Walker, for a while, was considered a major, likely candidate for the nomination circa June-August 2015, until his poll numbers, as well as Rubio's and Jeb's, dropped significantly with the rise of Trump, and he suspended his campaign in September; meanwhile, Jim Gilmore's campaign DID last all the way until he suspended it a week after the New Hampshire primary, but he was by no means a "major" candidate. He was at the bottom out of the 12 remaining GOP candidates, and he wasn't even included in any polls! He was only allowed on the UNDERCARD debate stage TWICE: the first one, and the last one).
Now, you very well could also make a second quiz specifically for candidates who dropped out BEFORE the primaries began (Rick Perry, Scott Walker, Bobby Jindal, Lindsey Graham, George Pataki, Jim Webb, Lincoln Chafee, and Larry Lessig).
