Scandal and Fraud
If you google "obama scandal" and "obama fraud" (no quotes) you get a total of about 127 million hits. Do the same thing for Bush and you get about 170 million. On a per year basis (Obama 3 years and Bush 8 years) that's about 42 million per year for Obama and 21 million per year for Bush. Anyone who claims Obama has no scandals or fraud is out of touch with reality. For a couple of specific Obama frauds/scandals, try "fast and furious" or "solyandra".
