I'll throw a little gasoline into the conversation...
If we remove right/left politics we have this
President Obama campaigned on reversing Bush era things like the patriot act, guantanamo bay, bringing an immediate end to Iraq, and regaining world trust of the US.
And what do we have now?
Accusations of the IRS being used for spying on political opponents, guantanamo bay still going strong, we still have people in Iraq and unmanned drone strikes have quadrupled.
Nixon spied on a few hotel rooms and was basically fired. Our current government is spying on millions of people and the people who voted for them are silent.
Ralph Nader well known (in the US) for exposing how unsafe cars were in the 60s and 70s, green party presidential candidate (too many times to count) claims President Obama is a worse "war criminal" than Bush.
"Change" isn't quite the word.
Senators and Congressmen get paid somewhere between 150 and 200k a year, but none leave politics without being multimillionaires. Legally they can invest in companies that they have oversight on regarding mergers. So they could buy a few million in stock and approve a merger and double their investment.
Perhaps in 2016 we'll get a real change away from business as usual politicians and fire as many people as we can.
