My question to folks like you who understand this reality: what is the actual mechanism which could be activated to remove a sitting president who is guilty of criminal acts, some of which are present day acts? If the House musters bills of impeachment, the Senate under Democrat rule can deny the trial on the grounds that he is not legally the elected president, but that doesn't remove him at that point.
That's not an easy question. America is increasingly a country of men and not a country of laws.
I don't know if Obama desires this drift, or is simply enjoying the benefits of it. Countries of men don't have formal mechanisms to remove bad leaders. They'll leave when their term is up, because they fear the wrath of other men, not because they fear the law.
Beyond that, I don't know what to tell you, other than to suggest you read up on how the Romans fared with issues of succession and removing corrupt leaders. This isn't the country you grew up in, but its change is nothing new. This path has been walked before by the republics of old.
