Hard to do...
The original PATRIOT Act passed the Senate by a vote of 99 to 1 I think. The Senator from Wisconsin was the only one to vote against it. Feingold I believe.
He was replaced by a more "law and order" type Senator. I still think to this day it was because he threw wrenches into all of these programs whenever he had a chance. (And sometimes even if he didn't have a chance, he would sabotage the machinery.)
The thing is ... the people of Wisconsin voted him out. Now you can argue that they didn't understand what they were doing... but you can't argue the vote. And this illustrates the problem.
In a nutshell...
There is little political profit in fighting these programs.
THAT, is what we need to find some way to change.
EDIT:
BTW, just a point of fact I think may be relevant here...
Wyden voted YEA for the PATRIOT Act.
Just Sayin'.
