I hate when people make me defend Obama....
The economy had already crashed when Obama took over....generally speaking the economy recovered greatly under Obama....
Obamacare is a disaster, my wife's insurance which went from being 100% covered by her employer to one of those plans that they couldnt keep and for that year we had to pay $300 a month to keep her covered until I could get her under my plan.
It recovered some, not greatly as evidenced by nearly his entire Presidency staying at 0% interest rate.
