You're getting way ahead of yourself, at least in Ohio.
Redistricting won't come about for another almost 10 years and the make up of the Apportionment Board won't be decided until the 2018 statewide election.
Republicans currently hold every statewide office, all Ohio Supreme Court seats except one, and have supermajorities in both the Ohio House and Ohio Senate.
Poised for a Democrat takeover?
Thanks, I Didnt know that. Didnt they cave on voter ID and some other fights?
