Because of the uniqueness of the last election, because the spending limit was pro-rated to the length of the election and those spending limits were so high, first, very few candidates spent to that limit, and second, many candidates got an initial reimbursement—which is designed to help them pay off their debts—that was greater than their end reimbursement. We had to chase a fair amount of money after the last election.
