I think the focal point should be on Hastert the guy with the ball and the other leadership in the House. Bush IS the PROBLEM and is thus beyond redemption. Also keep on calling your representatives and senators. Calling them is FAR more effective than zapping them e-mail or faxes. Call first then follow it up with e-mail and faxes. NumbersUSA has a good fax blasting site.
Oh and KEEP ON CALLING. They track the numbers of calls on issues. I have seen cases where representatives have changed their positions overnight on issues because of the volume of calls they have received. Remember, these people are up for reelection IN A FEW MONTHS. Make them FEEL THE HEAT.
