Mr Saunders, like many on the left sometimes seem to have capacity for evasion of reality with a coefficient of infinite elasticity.  President Obama is a colossal failure economically, in foreign policy, and in domestic relations.  

Economically he has  more than doubled the US national debt to $20 trillion, put 46 million on welfare, 95 million out of the workforce, an annual trade imbalance approaching $1 trillion, a real unemployment rate of 10%+ not the fudged GAO 6%, Obamacare as a  failure, and an inversion problem with manufacturing and finance operations under foreign registry due to high taxes and over regulation.  

The Middle East is in chaos with ISIS in 28 countries,  600,000 slaughtered,  a million refugees  mostly young Muslim men destabilizing western Europe, the Russians and the Chinese emboldened. Our allies no longer trust us  and our enemies neither respect or fear us. 

Black Lives Matter endorsed  by Obama with 25 police officers assassinated speaks for itself.
