Demrepdan,
My thanks to you for your thorough research. When I was in college at U Ky in the late 60s (the last time they elected a Republican to the governorship, by the way), the legislative elections were held in odd numbered years. It is interesting that they moved them to even numbered years, but I am sure it has improved turnout, especially for the vote that used to occur mid-way between governorship races. I also recall that they used to elect about twice as many cabinet offices as they do today.
It is interesting how the partisan balance of the two chambers is so starkly different. (
