No, of the current politicians, Nancy Pelosi is the most notable to come out against it:

I'd also argue that Sen. Rand Paul is more prominent than Ron Paul because he's a Senator...at least in terms of real influence. He's 1 out of 100 votes; a filibuster of the Senate variant of SOPA needs 40 votes.

Senator Ron Wyden has already promised a filibuster for PIPA.

The point is that without 40 more people on his side, they can just shut down Wyden's filibuster as soon as it starts.
