Obama
When Obama was running his campaign, I was really thinking he was something new, not just his face and color of his skin, but his ideas and the way he was going to handle the presidency. As a matter of fact he was showing signs of change and new ideas and different thinking, however as he got close to the end and started his presidency, specially in foreign policy, on a daily basis he looked like bunch of other politicians who are part of an old political tradition in US.
He still looks and sounds different from other politicians, to me the difference is in form and shape not in content.
This is a huge political system that absorbs and deforms people or pushes them aside, he could not get elected if he was loyal to the ideals of early days of his candidacy.
