Their book also notes Ohio's seemingly oversized role in presidential elections, possibly the nation's "quintessential swing state." Just in time for the Cleveland-hosted Republican National Convention this month and as the general election campaign heats up, a new book, "The Bellwether," examines Ohio's importance in picking the nation's president. History isn't a guarantor of Ohio's role, Kondik said, and the unconventional, unpredictable nature of Donald Trump's campaign could upset the norm. "Everyone knows that you can't get a Republican elected to the White House without carrying Ohio," state GOP chairman Matt Borges said this year, referring to the fact that none has yet. "If you look at the elections since 1964, the state's never been more of a bellwether that it's been since then."
