Leahy was the author of PIPA, so I'm not one to extend that umbrella. He has been a champion of civil liberties and other worthy causes, but that doesn't mean he gets a free pass on everything. If we blindly defend "our" side in two-party politics, we inevitably end up defending some pretty bad legislation. I'd rather assess each piece individually.
I misread your use of "our own" followed by a reference to the Tea Party. I still stand by my opinion, though, that we shouldn't give legislators a free pass on bad legislation just because we support the positions they have taken on other issues.
