History

Aurora County, named for Aurora, the Roman goddess of the dawn, was created by the Dakota Territory on 1 October 1879.[4] It was organized on 29 August 1881, when three county commissioners were appointed. The county had been established from the combination of former counties Cragin and Wetmore, which had both been formed in 1873. The three county commissioners met on 29 August 1881, and named Plankinton the county seat, an act which was ratified by voters in November 1882. The northern portion of Aurora County was partitioned off on April 17, 1883, and established as Jerauld County.[5]

The terrain of Aurora County consists of low rolling hills, partially devoted to agriculture. It is dotted with small lakes and ponds.[6] The highest point is the upper west boundary line, and the terrain slopes east-northeastward; the lowest point is the county's northeast corner at 1,325' (404m) ASL.[7]

Politics

Aurora County at one time favoured the Democratic Party and was one of just 130 counties nationwide to be won by South Dakota favorite son George McGovern, who grew up in adjacent Davison County. However, with the “Reagan Revolution” of the 1980s it has gradually turned into a strongly Republican county. The last Democrat to win a majority in Aurora County was Michael Dukakis during the drought- and farm crisis-affected 1988 election, and although Bill Clinton won a plurality in 1992, the county has since become as solidly Republican as most rural white counties in the US due to perceived lack of economic opportunity and differences with the Democratic Party's liberal views on social issues. Both George W. Bush in 2000 and 2004 as well as Donald Trump in 2016 beat the previous best GOP performance in Aurora County by substantial margins.
