Wyoming's economy is driven by tourism and the extraction of minerals such as coal, natural gas, oil, and trona. Agricultural commodities include barley, hay, livestock, sugar beets, wheat, and wool. It was the first state to allow women the right to vote and become politicians, as well as the first state to elect a female governor. Due to this part of its history, its main nickname is "The Equality State" and its official state motto is "Equal Rights". It has been a politically conservative state since the 1950s, with the Republican presidential nominee carrying the state in every election since 1968. A notable exception is Teton County, which has achieved notability for being Wyoming's most Democratic county and the only county in the state to be won by a Democrat in every election since 2004.
