Wow. This is a complete lie, absolutely disgusting, and exactly why GOP leadership has such a tight hold on the state. Ohio is one of the most gerrymandered states in the country and the GOP has controlled the maps (previously called unconstitutional by OH SC). What a joke.
Gerrymandering is almost exclusively a tool of Democrats. Last year in Ohio, they tried to enshrine gerrymandering in the state constitution by mandating district lines be drawn to consider party affiliation. Wisely, Ohio voters saw through the nonsense and soundly rejected it.
