Political control of Ohio has oscillated between the two major parties. Republicans outnumber Democrats in Ohio government. The governor, Mike DeWine, is a Republican, as are all other non-judicial statewide elected officials: Lieutenant Governor of Ohio Jon A. Husted, Ohio Attorney GeneralDave Yost, Ohio State AuditorKeith Faber, Ohio Secretary of StateFrank LaRose and Ohio State TreasurerRobert Sprague. In the Ohio State Senate, the Republicans have firm control, and in the Ohio House of Representatives the Republicans control the delegation. The Ohio Congressional Delegation is mostly Republican as well; twelve representatives are Republicans while four are Democrats. The Congressional map is gerrymandered, but in 2018, Ohio voters approved a constitutional amendment to limit how much the majority party could control the process of drawing congressional lines, beginning in 2022. One U.S. senator, Rob Portman, is a Republican, while the other, Sherrod Brown, is a Democrat. Most of the mayors of the ten largest cities in the state are Democrats. The Republicans are strongest in the rural Northwest, the affluent Cincinnati and Columbus suburbs, and have been making gains in Appalachian Southeast Ohio over the past decade. The Democrats rely on the state's major cities as well as Northeast Ohio, and have been making gains in educated suburban areas in recent years. Due to a close split in party registration and its historical electoral importance, Ohio is considered a key battleground state. The state was vital to President George W. Bush's re-election chances, because he won there by nearly four points in 2000 and because no Republican has ever been elected President without winning Ohio. In that election, Bush won the state with 51% of the vote, giving him its 20 electoral votes and the margin he needed in the Electoral College for re-election. The state was fiercely contested in 2008 and 2012 as well, with President Barack Obama winning narrowly on both occasions. Ohio is a bellwether state in presidential elections. Since 1860, Ohio has voted with the winning candidate, except for Grover Cleveland in both 1884 and 1892, Franklin D Roosevelt in 1944 and John F Kennedy in 1960. In 2016, United States presidential election, Ohio was won by Donald J Trump by a margin of 8.13 points. Ohio's presidential electoral vote total has been declining for decades. For the 2004 through 2020 presidential elections, it had 18 electoral votes, down from 21 in 2000 and down from a peak of 26 in 1968. Ohio now has its fewest electoral votes since 1828, when it cast 16. The state cast 3.71 percent of all electoral votes in 2004, the smallest percentage since it cast 3.40 percent of the votes in 1820. Ohio lost two electoral votes after the results of the 2010 United States Census, leaving it with 18 electoral votes for the presidential elections in 2012, 2016 and 2020. Ohio's large population has long made the state a major influence in politics. Seven presidents have hailed from Ohio, all Republicans: Ulysses S. Grant, Rutherford B. Hayes, James A. Garfield, Benjamin Harrison, William McKinley, William Howard Taft and Warren G. Harding. The General Assembly, with the approval of the governor, draws the U.S. congressional district lines for Ohio's 16 seats in the United States House of Representatives. The Ohio Apportionment Board draws state legislative district lines.
