Conceding an election is never easy. I know from painful experience. When I first ran for Congress in southern Arizona in 1982, everyone predicted a tight race, and they were right. By 1 a.m. on election night I was certain that my opponent had won. It was narrow — less than 3,000 votes — but I knew from looking at the numbers that we weren’t going to prevail, despite the never-say-die attitude of my staff.
