Ohio's state-level politics are dominated by Republicans (State Congress, conservative Governor). As for how Democrats have found success here in National elections... I'll leave that to your imagination.
Magpul would be pretty safe in Ohio. We have spent the better part of the last decade writing pro-gun law after pro-gun law, and recent events have not changed that trend.
The thing that hurts Ohio is our reputation as a 'union' state, which was certainly true 40 years ago, but like everywhere else, unionism has died a slow death here in the Buckeye state. Magpul would not have to worry about fighting union power here, because outside of the U.A.W., there is no union power to speak of.
