Both the Tea Party, and far Left despise Obama. The far right want him on trial for subverting the Constitution. The far Left think he should be put on trial for war crimes.
You would have to have the leaders of most of the countries of the world standing with him in Court. It's not "One" villain doing the harm. Rather a whole "World Culture of Capital Power Greed, and Institutional Stupidity".
As it is Obama is the least guilty of that lot.
Even the most 'idealistic' assuming power becomes part of the problem. Because they're inheriting a Horrifying "Game in Progress". One that seems so far "Immune" to reform.
Though it's lots of fun, and easy to do...
It would be wise if we finally got over our simple gut "solutions" to immensely complex problems.
