The 2008 United States presidential election in Ohio took place on November 4, 2008, which was part of the 2008 United States presidential election. Voters chose 20 representatives, or electors to the Electoral College, who voted for president and vice president.

Ohio was won by Democratic nominee Barack Obama with a 4.59% margin of victory. Prior to the election, most news organizations considered this state as a major swing state and bellwether. Both major party candidates visited Ohio extensively and campaigned throughout the state, trying to sway moderates and independent voters to their side. The polls in Ohio were fairly even throughout the campaign but Obama had a slight lead as Election Day drew closer. In the end, Obama flipped Ohio into the Democratic column. Obama's 2,940,044 votes are the most received by a Democratic presidential candidate in the state's history.

Despite this fact, Obama became the first Democrat ever to win the White House without carrying Pike County. On the other hand, Obama became the first Democrat to win Hamilton County since 1964. , this is the last election in which Lake County, Monroe County, Belmont County, Tuscarawas County, and Jefferson County voted for a Democratic presidential candidate.Sullivan, Robert David; ‘How the Red and Blue Map Evolved Over the Past Century’; America Magazine in The National Catholic Review; June 29, 2016

Ohio is also one of only three states that backed Obama twice that would go on to vote against his vice president Joe Biden in 2020, the other two being Florida and Iowa.

Polling

During most of the summer and September, McCain led many state polls, many by 50% or more. Rasmussen had McCain leading with as high as 51% in September. But many voters in the state changed their minds as Obama later gained a steady lead in most polls taken starting in the beginning of October (around the time of the 2008 financial crisis).Election 2008 Polls - Dave Leip's Atlas of U.S. Presidential Elections

Fundraising Obama raised $7,218,801. McCain raised $5,682,839.

Advertising and visits In a major swing state, Obama spent over $28 million to McCain's $24 million. The Republican ticket visited the state 28 times, compared to the Obama ticket's 22 times.

Analysis Going into the election, both McCain and Obama knew that Ohio was a crucial state. Earlier in the primary season, Ohio had given a major comeback victory to Hillary Clinton. Both candidates campaigned heavily throughout the state in hopes of winning its 20 electoral votes. As no Republican has ever won the presidency without winning Ohio, it was seen in particular as a "must-win" state for McCain. George W. Bush's narrow wins in 2000 (by 3.51% against Al Gore) and 2004 (2.10% against John Kerry) proved critical in Bush's narrow wins nationally.

Obama won Ohio's 20 electoral votes by a margin of 4.59%. Obama's win in heavily populated areas such as Cuyahoga County (Cleveland), Franklin County (Columbus), Lucas County (Toledo), Montgomery County (Dayton), Summit County (Akron), Stark County (Canton), Mahoning County (Youngstown) and the traditionally Republican Hamilton County (Cincinnati) greatly contributed to his victory in the state.

McCain did best in the Republican base in the center and western regions, composed of relatively rural areas combined with Cincinnati and Columbus' heavily Republican suburbs. In addition, McCain won all but four counties in the Appalachian southeast, mirroring the troubles Obama had throughout this region. On the other hand, Obama did best in the Democratic base—Cleveland (where he won almost 70% of the vote), Youngstown and the heavily unionized counties next to Pennsylvania. However, he was unable to significantly improve upon John Kerry's performance in these areas. More surprisingly, the cities of Cincinnati and Columbus gave Obama strong support. Cincinnati, the only major city that didn't vote for Franklin D. Roosevelt in 1940, voted Democratic for the first time since 1964. Columbus, a city shifting to the Democrats, also voted for Obama by a three-to-two margin. In addition, Obama won several northern counties along the shore of Lake Erie that John Kerry had lost in 2004.

As polls closed and results were coming in on Election Night, Republican strategist and adviser Karl Rove joined Brit Hume on Fox News offering analysis. Rove was discussing the impact an Ohio loss would have on McCain's chances of winning the election. "If he loses Ohio," Rove stated of McCain, "he goes from 286, which the Republicans carried in 2004, down to 266, and that puts him below the 270 threshold needed to win the White House. So he'd not only need to sweep the rest of these states which were won by the Republicans in 2004, he'd also need to pick up something as well." In an untimely moment, Hume broke in. "Guess what Karl," Hume interrupted, "I've just received word that the state of Ohio has gone for Barack Obama."
