Fair point and you can look at examples elsewhere in politics and business.  TPP is a great example of something that went through iteration after iteration before finally being rammed through.<p>CISPA and its predecessors were similar.  The entities with a vested interest in having these things come to pass have essentially endless coffers to take the long view.  All they need is to succeed once whereas we need to succeed in stopping these things each and every time.  It is a war of attrition.
