Obama is first and foremost a politician. His speeches and his actions are not together.
His campaign speeches have been contradicted by his actions.

These contradictions can be enumerated but most people know what they are.

1. Gitmo
2. Iraq
3. Rich tax cuts
4. Nuke energy
5. Wall Street Advisors (his cabinet) and financiers (for his re-election)

There are more.

Watch for the notorious "Gang of Six" to destabilize Medicare, Social Security and Medicaid.
