There are people who believe that Barack Obama is kind, just and good, and thus are going to have a hard time believing that he's embracing some of the most abusive Bush/Cheney policies even when he does it right in front of their faces. Others aren't ever going to object to what Obama does in this area, because they believe (as Bush supporters believed about Bush) that there's nothing really wrong if Obama wields these same powers since Obama is a kind-hearted ruler and therefore can be trusted not to abuse these powers. As DCLaw pointed out yesterday, people with that swooning mentality can't be reached because they don't really believe in the basic premise on which the country was founded, as enunciated by James Madison in Federalist 51:
Ambition must be made to counteract ambition. The interest of the man must be connected with the constitutional rights of the place. It may be a reflection on human nature, that such devices should be necessary to control the abuses of government. But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself.
We don't place faith in the Goodness and kindness of specific leaders -- even Barack Obama -- to secretly exercise powers for our own Good. We rely instead on transparency and on constant compulsory limits on those powers as imposed by the Constitution, by other branches, and by law. That's what it means to be a nation of laws and not men.
When Obama embraces the same abusive and excessive powers that Bush embraced, it isn't better because it's Obama rather than Bush wielding that power. It's the same. And that's true even if one "trusts" Obama more than Bush.
