Yeah, but based on the guiding principle of democracy (govt by the will of the people), you'd hope to see them do that immediately instead of waiting years and years to do it when it is most strategically advantageous. I know politics is gamey like that by nature, but it sucks to see. The lag time between a policy becoming overwhelmingly popular and it actually being implemented is often long enough to radically alter the course of millions of peoples' lives.
While this is true, I'm not going to look a gift horse in the mouth. At some point, we decided as a nation to only care about politics during election years. Participation rates for local elections is near an all time low. If people were more involved with the process, I would imagine that we would see more movement in Congress as a reaction to the will of the people.
