Mason County was at the time of the Civil War the easternmost of the strongly secessionist Bluegrass bloc.[11] Mason was in fact the most easterly Kentucky county to be represented at the Russellville Convention of 1861 to discuss the secession of Kentucky from the Union.
Mason County's secessionist sentiment meant that it voted Democratic consistently up until the 1950s, with the exception of the 1928 election when strong local anti-Catholic sentiment against Al Smith allowed Herbert Hoover to carry the county. Since 1996 the county has shifted more strongly Republican in US presidential elections.
