SOPA Opera [http://projects.propublica.org/sopa/] shows a list of senators and representatives and their stances for or against SOPA and PIPA respectively.

I checked the website this morning just to get a feel for our starting point and it was:

  ~80 for
  ~30 against

Just now I checked it again and saw:

  70 for
  64 against

This is amazing! What great progress (although we need more), and what an amazing tool for keeping track of our Congress!
