Ducey’s move to back Taylor Robson comes as early voting began this week ahead of the state’s August 2 primary. It also thrusts the governor back into a political showdown with Trump in a now two-year clash over election lies about the Arizona election system. By choosing to back Taylor Robson, Ducey is throwing his considerable Arizona political force behind the strongest challenger to Lake. Despite Trump’s ire, Ducey has remained a popular figure in Arizona among moderates and establishment Republicans, even as the former President maintains a strong hold on the Arizona GOP base. Last week, Taylor Robson earned the endorsement of former US Rep. Matt Salmon, a day after he ended his bid for the GOP gubernatorial nomination.
