Obama Presidency News

From what I can determine, Obama is a man of his generation, where, self gratification and moving ahead is the directive.
I know what McCain has done, five years of torture, and, as a Senator, deriding his own party, to his demise in 2000.
What has Obama accomplished? Lying about campaign finance reform? Going to the center after embracing those that would do anything but?
Please, tell me, how has Obama sacrifieced himself on behalf of his nation, and, not his ambition?

I keep hearing Obama saying people and businesses need to make tough painful sacrifices to come out of this economic downturn, What sacrifices has he and the government made both collectively and personally ? Have any of them taken pay cuts ? Or give up perks ? Cut back on spending such as that appropriated in the stimulus for fancy government buildings ? Just curious. Or is this more of Obama's " Do as I say, Not as I do " jargon. Thanks in advance for your answers.
