President Trump has narrowed Democratic presidential nominee Joe Biden’s lead in Arizona to within 1 percentage point less than a day before the election, improving his standing with Independent voters and once-wavering Republicans, a new poll shows.

Biden holds a 0.6 percentage point advantage over Trump, 45.9% to 45.3%, according to results from Data Orbital’s tracking poll published on Monday. It’s the first time Trump has been within a point of Biden, who held a 5.2 percentage point lead over him less than two weeks ago.
