Stuck in Second

Bush approval ratings at an all time low. What is interesting is the related chart that tracks poll percentages for the last 5 presidents excluding Bush1. The concerns for Americans under Republican presidents all deal with 3 overwhelming concerns - international relations, scandal, and economy. Do we see the pattern here?

Speaking of scandals: It has been 24 days since the American Public learned that one Karl Rove leaked the identity of a covert CIA agent.
