Brief notes on contacting Congress or the White House:
1) Email is pointless. Don’t even bother.
2) Phone calls are good, but tend to be boiled down to a “yes” or “no” stance on a particular issue. Calling local/state level offices is more effective as they receive less volume and are slightly more receptive.
3) A handwritten* letter is best of all, but don’t mail it; ever since the never-to-be-solved anthrax attacks of 2001 it takes weeks for snail-mail to get to the Capitol. Instead, write out a brief one-page note, sign it, scan it, and fax it over. If you don’t have access to a fax you can use FaxZero to send 2 free faxes a day, though you’ll need to save the scan as a DOC or PDF. This can be done by opening the scanned image (jpg or etc) in Word, OpenOffice, Acrobat, or etc. and then re-saving it. Then you have a file laying around that can be re-faxed on a daily basis.
*don’t know why, but DC lore says handwritten is best. Presumably because it indicates a greater degree of effort has gone into the communication.
