Since becoming president, Obama has really not done one thing that he promised to do.
On every single issue, the Republicans have thrown an endless temper-tantrum, and rather than get anything done, Obama has chosen the path of moderation and compromise, which is precisely what the Republicans want him to do. Even Obama's infamous health-care bill, is nothing more than a watered down ineffective mirage.
Ultimately, the result has been a failed administration, which is unable to do anything positive, because it refuses to denounce bipartisanship, and it insists on continuing to cooperate with the deliberately destructive Republican party.
