When the 2020 vote is certified, new records for the closest presidential election will have been set in two states. Joe Biden’s victory margin over Donald Trump in Arizona currently rests at 0.31 points – well below the previous mark set 56 years ago when native son Barry Goldwater defeated President Lyndon Johnson by 0.99 points in 1964. Meanwhile, Biden’s 0.28-point margin in Georgia is less than half the size of Bill Clinton’s 0.59-point win in the state over George H.W. Bush in 1992.
