Wisconsin, Iowa and other states to watch closely on election night
President Donald Trump and Democratic challenger Joe Biden each have a path to win the White House. The former vice president is competitive in all the battleground states Trump carried in 2016, and has put a handful of traditional Republican states, including Georgia and Arizona, in play. Trump can win by defending a wide swath of territory he won in 2016, but his hopes for reelection are heavily dependent on the swing states of Florida and Pennsylvania.
