Just found THE BEST interactive website where you can see who in the House and/or Senate is likely to support/oppose SOPA/PIPA. Sort by Party affiliation, state, CAMPAIGN CONTRIBUTIONS, etc. MOST EXCELLENT!! Click HERE to link to it...

The link is HERE.  Be advised---the site is explicit when it says these are representative/senators that have either signed on as sponsors of the bill(s) or based on previous statements or voting records are likely to vote for or against these bills.  It DOES NOT show all the members of the House and Senate, but it is reveals the inertia of the direction voting might go.  The Senate seems to be the real problem for the opponents of the bills...

Also, PC WORLD has an excellent primer that is pretty impartial on the issues that surround these two bills. Very short and covers the high and low points..
