One can only hope Obama is heading for impeachment prior to the total destruction of American foreign policy and the economy.
If it’s constitutional, since we must follow the document Obama enjoys wiping his rear end with, we have cause for impeachment for:
Malfeasance
Ineptitude
Dereliction of Duty
Economic Terrorism
Making treaties without consent of Congress
If you believe that Obama does not meet the constitutional requirements to be POTUS that opens up another huge can of worms.
Obama needs to go, we can not afford 4 years of his policies let alone 4 months.
