I have actually gotten a few responses from politicians of all levels.
The ones I got from my Senators were about what I expected them to be as I already know where they stand on firearms. Sherrod Brown gave a very generic but anti leaning reply, Rob Portman had a pro-gun reply.
Have yet to receive anything from my Congress person Marcy Kaptur. I know where she stands on gun rights. Still would be nice to get some sort of acknowledgement even if its to tell me to she thinks we should revert back to sticks and slingshots for self defense.
Honestly I feel the responses I have gotten from the state level and local level are a bit more sincere and heartfelt than anything I will ever see coming from the federal level.
