The Great Plains states of North Dakota, South Dakota, Nebraska, and Kansas have been strongholds for the Republicans for many decades. These four states have gone for the Republican candidate in every presidential election since 1940, except for Lyndon B. Johnson's landslide over Barry Goldwater in 1964. Although North Dakota and South Dakota have often elected Democrats to Congress, after the 2012 election both states' congressional delegations are majority Republican. Nebraska has elected Democrats to the Senate and as governor in recent years, but both of its senators have been Republican since the retirement of Ben Nelson in 2012. Kansas has elected a majority of Democrats as governor since 1956, but has not elected a Democratic senator since 1932. From 1997 to 2010 and again since 2019, Kansas has had at least one Democratic House member (two in 2007 and '08).
