You rang? I am The Tack, Big Blue Corpuscle for Conservative Justice!
I got to hear Tom Tancredo Saturday evening exhort us to continue harrassing our representatives because our input does shape their actions. That was very heartening to hear. NumbersUSA, your own emails and real mail shape policy. Without it, to paraphrase a bad phrase, the scumbags will have already won.
Bitch, moan, pitch a tantrum or send a polite note. Otherwise your reps only have special interests' word that the invasion is fine with everyone. If you don't tell them otherwise you'll only have yourself to blame when they come looking for your candy to stuff in their pinata.
