Power corrupts ......

Russ Roberts writes at the Cafe Hayek blog

Go back to the campaign of 2008, McCain (remember him?) and Obama. Suppose in the middle of the campaign, someone returned from the future and told you that by 2011, the President of the United States will have kept Guantanamo Bay open, launched a war against Libya, and crossed covertly into an ally’s territory to assassinate Bin Laden. Who would you think that would be? McCain or Obama?

To me Obama has ended up looking a lot like Bush on these matters. Roberts asks

What happened?

and comes up with three possible answers,

Three possibilities come to mind. The first is that politicians on the campaign trail lie and dissemble. They need to motivate their base, craft an image, and so on.

The second possibility comes from a CIA economist who told me in the middle of the 2008 campaign that when Obama becomes President, he’ll know what Bush knows (meaning horrific and frightening classified information) and he’ll do the same thing as Bush.

The third possibility is that when you get into power, you change. It’s fun to play video games with real lives. You can’t help yourself. It’s easy to convince yourself (given that classified information) that you have no choice.

Roberts goes for a combination of 2 and 3 as the answer and I would have to agree, with an emphasis on 3. What I don't get is why people seemed to think Obama would be different as president. Power corrupts ..........
