2008 United States presidential election in Ohio candidate Barack Obama
Analysis
Going into Election 2008, 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 for 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 3.50% against Al Gore) and 2004 (2.11% against John Kerry) proved critical in Bush's narrow wins nationally.
On Election Day 2008, Obama won the Buckeye State'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 him strong support. Cincinnati, the only major city that didn't vote for Franklin D. Roosevelt, 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."
