Arizona: Biden 50, Trump 45

Back in March, the last time NBC News/Marist measured Arizona, Biden topped the president by only 1 point, 47 percent to 46 percent.

Biden’s current lead over Trump is fueled by his advantages among Latinos (61 percent support him, versus 31 percent for the president), voters under 45 (57 percent to 36 percent), women (57 percent to 38 percent), independents (55 percent to 38 percent) and whites with college degrees (51 percent to 44 percent).

Trump, meanwhile, is ahead among men (53 percent to 43 percent), those ages 45 and older (52 percent to 45 percent), whites (49 percent to 46 percent) and whites without college degrees (52 percent to 43 percent).
