Obama Bin Laden far and away
But Bush owns the debacle in Iraq and the secret laws and the secret courts.....the remaking of DOJ into the agency of the oppression of the American people.
Clinton Corp started the identity politics and sabotaged all in the D party who might challenge them, letting only the sycophants stay.
Biden spent his entire career as a shill for the Victim Culture Cult, finally, bringing the WOKE Revolution to intimate power by taking the executive branch while lying about what he is.
But Ya....I think Obama is my answer as well.....he was a Revolutionary figure, only constrained by Old America not being quite ready to fall, so he set about weakening it at the right points so that it would fall....that is the project that he put his alleged great intellect on.
