Don't do this, it's pointless if you complain about Republican elected officials they typically just try to siphon resources away from your area. If you really think this will work please use a false identity to avoid being targeted.
I live in rural western Ohio. My Representative and Senator are both likely to turn a deaf ear to my concerns. I still see value in making sure that their office has knowledge of my concerns and position. Maybe it won't change their position on a particular issue, but their staff is definitely interested in keeping tabs on the opinions of their constituency.
My advice if you don't believe this is true, just ask! They are very open about talking about this and feel that Democrats do the same thing.
