These states could decide the US presidential election
These states will play a critical role in delivering the 270 electoral college votes needed to win the White House
The US presidential election will be decided by about a dozen states that could swing for either President Donald Trump, a Republican, or Democratic challenger Joe Biden.
These states will play a critical role in delivering the 270 electoral college votes needed to win the White House. Due to a surge in mail voting amid the coronavirus pandemic - as well the states' varying rules for when ballots can be counted - the results may not be known on Election Day, Nov. 3.
