I've received those same form letters in response to my letters and calls. You're right, they refuse to address the problem, though they are fully aware that almost 80% of Americans want tighter border controls, less immigration and no amnesty. I refuse to donate ANY money to ANY politician who won't defend America's borders (most of them).
Same here. I'm not even a reistered republican anymore.
I wouldn't mind contributing to them if they were trying to do something about the problem. But they're not. They flat out refuse to enforce our federal laws. The very laws they are sworn to uphold. They will get no support or money from me..
