Folks, I've worked with my own U.S. Congressman on a couple of issues, and I know for a fact the letters he receives are, at the very least, skimmed and counted one way or the other. People are assigned to collect the better-written letters as representative samples from all sides of an issue, and he himself randomly selects samples from the entire stack.
At the very least your letter is skimmed and counted. If it's well-written, or if you're just plain lucky, it might actually be read.
So please keep those letters to your local, state, and federal legislators coming!
They DO make a difference.
Case in point.
I just got a reply from my state congressman on constitutional carry.
it happens. haven't tried with US congress yet. In WA it's useless to even try to get these loons to do anything pro-2a.
