(NEXSTAR) – Voters are heading to the polls to cast their ballots Tuesday in the 2024 presidential election, a contest that will make history in the event of either a Harris or Trump victory. Should Vice President Kamala Harris win, she would become the nation's first female president, while a Donald Trump victory would make him the first former president since 1892 to lose the White House and take it back in non-consecutive terms. A Trump reelection would also make him the first U.S. president convicted of a crime to win office. Can you vote in person if you were mailed a ballot? Emotions around the contest have been rising over the past four years, which saw (among other critical events): rioters storm the U.S. Capitol on Jan. 6; the dismantling of Roe v. Wade; Trump's unfounded election denial; simmering anger over the U.S.-Mexico border; war in the Middle East; two assassination attempts against Trump; and Harris' last-minute entry into the race.
