Here they are. I can't take credit for them as I found them on someone's blog, who found them on someone's website or blog. Anyway, for what it's worth, I think it's a good idea to contact these people too. Because they may not otherwise be able to see both sides of this issue, you know? Anyway, here is the list I found:
Jennifer Fuson, Consumers Union (202) 462-6262
Rachel Weintraub, Consumer Federation of America (202) 387-6121
Ed Mierzwinski, U.S. PIRG (202) 546-9707
David Arkush, PC (202) 550-0107
Celia Wexler, UCS (202) 331-6952
Here is the blog article I found them on:
