If you think this country needs to change direction, get out and vote! We need a Congress that will hold Bush accountable and a Republican majority has proven that they're not going to do that.
Sadly, it's not enough to just vote for good candidates. Because of the way the Republicans have changed the rules, only a majority of the majority can enact legislation. So, to change direction in this country, we need to get the Democrats to be a majority in at least one chamber of Congress.
I've done what I can by volunteering with MoveOn.org's Call For Change program in their San Francisco office, recruiting volunteers and calling voters directly, encouraging them to get to the poles.
For the sake of Iraq, the environment, the federal deficit, cronyism, good governance, our international standing in the world, etc., we need a change.
