Obama lost all trust and credibility with the American people well before the disaster that is Obamacare

Obama lost all trust and credibility with the American people when he :- 

Failed to prosecute Bush & Cheney for war crimes 
Failed to investigate 9/11 
Failed to prosecute for the lies told as to the reasons for launching the war on Iraq 
Failed to jail the senior bankers for their multiple frauds 
Appointed ex Monsanto employees into the FDA 
Appointed Tim Geithner as Treasury Sec 
Bailed out Goldman Sachs AIG bets at 100c on the dollar with taxpayer money 
Allowed the Fed to embark on QE which just makes the bankers richer & actively prevents job creation 
Increased military spending to above even Bush levels 
Continued with $1.3tn of annual Corporate Welfare 
Increased taxes on middle earners and below 
Failed to uphold the Rule of Law 
Continued the Bush programs of destroying civil rights and expanding Mass Surveillance 
Expanded the drone warfare program which has recruited millions more Islamic Extremists 
Signed the Monsanto Protection Act 
Negotiated the subjugation of the American people to Corporate profits in the secret TPP & TAFTA "trade" treaties
Supported Islamic Extremist terrorists in Libya and Syria
Launched his war on whistle blowers, journalism and transparency 
Declared that Magna Carta no longer applied to Americans or anyone else in the world
Repealed Posse Comitatus to allow US troops to operate on the streets of American cities. Just as Julius Caesar had done 2,000 years before when he crossed the Rubicon.   
Used the FBI to harass and intimidate Occupy protesters and the NYPD to beat them up. The FBI branded Occupy as "Domestic Terrorists".

Etc. etc. etc.
