If you see an excessive scandal problem,... it is that you have decided to pay attention...
Bush, Clinton, Bush, Reagan, Carter, (Ford, came away fairly clean), Nixon, LBJ, Kennedy...
When did you start paying attention?...

...
Make a list of Obama's scandals.... and show me how many involve unilateral action... and how many are either continuation of established protocol, or a compromise with Congress...(particularly the Right side of Congress)...
I can find many dozens from the Reagan, and GWB era... all unilaterally original in action and thought...
Invention of scandal is an election tactic...
