Since Obama,

More workers have left the job force than ever in history
More families are on food stamps than ever before
More families live at poverty level than ever before
More blacks are unemployed than ever before
More black babies aborted last year than born
Abortions subsidized unconstitutionally by gov for the first time.
The national debt has/will double
More terrorist attacks than ever before
More businesses have gone under and not come back
First time a president has declared leading from behind, which really means "following".
America is no longer world leader, first time.
First time a president has deemed cops to be the enemy, ever
First war on Christianity by white house
Worst racial division widened by a president.
First death list, to include Americans
First president to leave Americans overseas to die at hands of radicals, with no assistance attempted. Lied and blamed it on video.
First gov enforced purchase requirement of product. Health Insurance.

The list is actually at least five times this long, but I think you get the idea. Obama is the worst of failed experiments in American history.
