For those contemplating contacting their congresscritters, or other elected officials:
It used to be, and I suspect it is even more true now, that real, snail mail letters counted about twice as heavily as other modes of contact. I guess the thinking is that, if someone takes the time to write or type out a letter, address an envelope, put a stamp on it and mail it ... the issue must be important to them. Other forms of contact, such as fax, phone, or e-mail, are undeniably faster and easier -- and for that reason don't count as much.
If you write (by whatever medium): keep it short. Remember, your congresscritter is NOT going to read your letter. Some minimum wage letter opener drone will open and read your letter, and will then put a check mark in a column on a tally sheet for that issue. So -- open your letter by CLEARLY stating your position. Then write a brief paragraph or two explaining your views. Close by re-stating your position.
That's it. If it's too long, they just ignore it.
