Ohio's presidential election history offers reasons why adding an Ohioan to the national ticket could be tempting for either party's nominee:
Ohio's been one of the most hotly contested battleground states in the last three general elections, clinching re-election for Republican George W. Bush in 2004 then delivering twice for Barack Obama.
No Republican has won the White House without Ohio; John F. Kennedy in 1960 was the last Democrat to do so.
The last time an Ohioan appeared on a national ticket, it helped: Republican Thomas Dewey won Ohio by less than half a percentage point over Franklin D. Roosevelt in 1944 with Gov. John Bricker as his running mate. Without Bricker in 1948, Dewey lost Ohio to Harry Truman by an even narrower margin.
