Apologies if this has been done before, I tried some keyword searches.
Basically I was thinking about the possibility of a state where the governor is more of a ceremonial role and real executive authority rests in the legislature. This could be an OTL state or an alternate one.
While I'm putting this in pre-1900, I can see some 20th century PODs as well. DC gaining statehood with a weak mayor and a strong city council, for example, and that's more likely to take place in the 20th century. If it doesn't ruffle any feathers, feel free to include any post-1900 ideas here as well.
