The Washington Post’s new polling averages show Donald Trump is leading in 5 of the 7 battleground states that are most likely to determine the outcome of the election. The polls are particularly close in Pennsylvania, Wisconsin and Michigan, meaning the average is within a normal-sized polling error of 3.5 points and either a Trump or Biden victory is plausible. In the other four battlegrounds — North Carolina, Nevada, Arizona and Georgia — Trump’s polling leads are larger, but the race is still close.
