As the 2020 elections hurtle toward their finish, Gallego has emerged as a key Arizona Democrat to watch. He was among the few surrogates on hand for the Biden campaign during the first presidential debate in Cleveland. He is a member of Biden’s Latino Leadership Committee and has spoken — virtually — to Democratic groups across the country, from Fresno, Calif., to Polk County, Iowa. Before the new coronavirus crisis wiped it out, Gallego helped secure a Democratic primary debate in Phoenix that was scheduled for March.
