Barber cruised to victory on Tuesday night in a special election to succeed his one-time boss, former Arizona Congresswoman Gabrielle Giffords, who retired in January to focus on her recovery from a gunshot wound to the head.
Barber, 66, Giffords' handpicked successor and a former aide in the House of Representatives, led with 52 percent of the vote.
