34 scandals and nothing on him
Salon provides the list, and that's just one term.
They note:
If the next four years of Bush and the GOP running the federal government are anything like the previous four, however, potential scandals will lead to few political consequences for the Republicans. Bush opponents will likely be disappointed if they are waiting for a renewal of the supposed "second-term scandal jinx" dogging Richard Nixon, Ronald Reagan and Clinton.
After all, Washington Republicans are insulated by a rabidly partisan Congress with no interest in investigating the executive branch (and little taste for disciplining itself). By contrast, presidents Nixon, Reagan and Clinton each faced an adversarial Congress. As the late Senate Watergate Committee counsel Sam Dash noted in 2003 about congressional oversight: "Although it worked then, it doesn't mean it would work now."
