Ohio
Ohio was the first state admitted under the Northwest Ordinance, entering the Union in March, 1803. It participated in its first presidential election in 1804. Ohio has been a major battleground in recent elections due to the closeness of the vote and its wealth of electoral votes (currently 18). This was particularly true in 2004, when the state put George W. Bush over the top in a close 2 percent victory over John Kerry. 2016 saw Donald Trump defeat Hillary Clinton by over 8 points, the largest here there since 1988. Trump won over Joe Biden by a nearly identical amount in 2020.
The Buckeye State has proved itself to be a remarkably good presidential bellwether, although the 13 election streak of siding with the winner was broken in 2020. Ohio has been growing more slowly than the rest of the country and it has lost about 1/3 of its electoral vote clout since the 1960s. It will lose an additional electoral vote in 2024.
