I have to ask one thing tedster; if it were YOUR site, would you even make the paginated pages available for indexing? Or would you noindex them?
It seems that they just have a list of signatures as well as a BRIEF version of the petition description, which is a truncated version of the description that already appears on the main page (the page he is trying to rank).
