Which political party dominated Kentucky state politics from 1931 through 2003?

The Democratic Party dominated Kentucky state politics from 1931 through 2003. During this period, Democrats held the governorship for most of the time and maintained a strong presence in the state legislature. The party's influence began to wane in the late 1990s, leading to a more competitive political landscape. This shift culminated in a Republican resurgence in the early 2000s.
