By pure personal honesty levels (as opposed to systemic corruption due to corporate funding of elections), our Congress is a model of ethics. Look at Torricelli-- he went down based on a few thousand dollars of gifts, which is one of the largest scandals of recent years. Local government officials are routinely caught taking far larger amounts-- actually, a few connected to Torricelli in local New Jersey government are going down for exactly those kinds of corruption.
One reason why a Democrat won the governorship of Arizona is that the GOP had a series of corrupt governors who discredited the party. (Not that the Dems haven't done the same in other states).
