Lawrence Lessig makes a good point about integrity:
The source of America’s cynicism is not hard to find. Americans despise the inauthentic. Gregory House, of the eponymous TV medical drama, is a hero not because he is nice (he isn’t) but because he is true. Tiger Woods is a disappointment not because he is evil (he isn’t) but because he proved false. We may want peace and prosperity, but most would settle for simple integrity. Yet the single attribute least attributed to Congress, at least in the minds of the vast majority of Americans, is just that: integrity.
But with reelection rates as high as they are, voters forget all about integrity in the ballot box.
