The American people tend to trust their government and it is remarkable that they do. The biggest impact on fixing government will be the fourth P - the public who vote with their ballots, dollars and their feet.
It is beyond question that government has gotten big and at what point will people say enough is enough. The tea party movement is apparently a step in that direction. It remains to be seen whether they will have an impact.
Rather sadly the state of government depends on election cycles and we have to wait until the next election cycle to see if there will be major changes.
