Polling averages show Trump gaining on Biden in most swing states.

The deadline for early voting ends Friday in several states where the race is tight, including Arizona, Georgia, Nevada and Texas – and on Saturday in the key states of Florida and North Carolina. Though early turnout appears to favor Democrats in many states, Republicans are gaining ground quickly in Florida and other early voting states.

If the states end up breaking according to their current polling averages, and assuming the non-swing states go the way they did in 2016, Biden would win decisively in the Electoral College, even if he lost Ohio, which is tied. But Biden’s polling average advantage is greater than 5 points in just four of twelve swing states and the race will hinge on what happens in the races where Biden’s margin is thin enough to leave the candidates in a virtual dead heat.
