Every year Judicial Watch posts its assessment of the Ten Most Corrupt Politicians which includes those in high level office or running for high level office.
The lists are really interesting. The links also take you to the 'dishonorable mention' folks who didn't make the top ten.
It is interesting to see how the fortunes change somewhat as the party power shifts.
