For those who have yet to do it, I should point out that there is a PayPal donate button to support this effort that you are shown after submission of your entry. Send cards to all your representatives, then send those nice folk a couple of bucks to cover the postage at least.
However, I've now donated $5 because of the selfless thing they are doing. Thanks to everyone at SendWrite for doing this, hopefully it will help!
Supposedly, the constituent contacts that carry the most weight are in-person visits to the congressperson's office, contacts from people authorized to represent groups of constituents (like mayors), individual letters that are not copied from a form, and individual phone calls that are not read from a script.
If anyone has a reason to be in Washington, calling the office of your congressperson and scheduling a meeting with their staff during that time will be very helpful, especially if your congressperson is on a relevant committee, in this case the House and Senate Judiciary Committees.
