Seriously no republican has anything to gain from supporting PIPA or SOPA. The industry pushing for this are overwhelmingly backers of the democratic party, and will not only back democrats regardless, but will be inclined to uses their new found powers to shut down conservative speech.
Any republican that support this great expansion of federal power is either an idiot or is trying to kill the Conservative movement, by both hypocritical and arming its enemy’s with the means to shut down speech by that which they do best(false accusations).
Thank you for posting that link. Both my liberal democrat Senators of Oregon are on the no side. Thank you Wyden and Merkley.
