Brendan Nyhan wonders why the president has had no major scandals. He insists "the first Obama scandal is likely to arrive sooner than most people think":
Obama has been extremely fortunate: My research (PDF) on presidential scandals shows that few presidents avoid scandal for as long as he has. In the 1977-2008 period, the longest that a president has gone without having a scandal featured in a front-page Washington Post article is 34 months – the period between when President Bush took office in January 2001 and the Valerie Plame scandal in October 2003. Obama has already made it almost as long despite the lack of a comparable event to the September 11 terrorist attacks. Why?
It couldn't be because he is not corrupt and that that standard has trickled down?
