Consistently, Ohio is a battleground state in presidential elections. No Republican has won the office without winning Ohio. This trend has contributed to Ohio's reputation as a quintessential swing state. At the state level, however, Republicans are currently dominant. With the exception of one justice of the Supreme Court of Ohio, all political offices open to statewide election are held by Republicans. Republicans have a majority in the Ohio House of Representatives and a supermajority in the Ohio Senate. At the federal level, Ohio currently has one Democratic and one Republican U.S. Senator. As a result of the 2012 elections, 12 of Ohio's 16 members of the U.S. House of Representatives are Republicans.
