I did the same thing a couple of years ago when I realized what we had elected in 2000. I send the GOP beg letters back, writing "ask Mexico for money" in bold.
I do the same thing. Sometimes, though I tell them to stop asking ME for money; get it from the illegal aliens instead. Or I tell them I'm going to send money to Tancredo or the Minuteman Project instead. I actually look forward to getting those beg letters now.
