I think it is sad that people are so disillusioned that, like you, they have become unwilling to trust anyone. I am not that way.
I actually believe that most of the Republicans, and a few of the democrats, actually are trying to do their best. I will trust Bush and Cheney, until I see them do something unethical. I doubt I will be proven wrong.
Maybe after a few more years you will regain some faith in your fellow man. I hope so, because we are all in this enterprise together, you know.
