He was selected as a delegate to the territorial Republican convention in 1888.[5] He was elected as a Republican to represent short-lived Logan County, first at the Idaho Constitutional Convention in 1889,[6] then in the first session of the Idaho House of Representatives, which lasted from December 1890 to March 1891.[7] [8]
