It might be one of looking at local issues and figuring out who might best solve immediate problems. That is what I think it is. I don't think everyone is blindly trying to send an unknown message to Washington, DC. Although losing a republican congressional seat in New York to a Democrat might send a message to the GOP to get their merde together.
Right now I am seeing a lot of people who I never thought would be in economic trouble suffering horribly. These are people I have known for may years. Getting this economy in better shape is the most important thing we can do and that is a message for all political persuasions.
