Just because a president manages to scrape together a second term win doesn't mean that he is a successful. Popularity is not a sure sign of a good president, and in the case of Obama with the massive cheating that went on last year we can't even be sure that he truly won.
The damage the Obama has wrought upon our nation is on par with both Pierce and Buchanan. We never truly recovered from the last recession thanks to bone headed and ham fisted policies that time has shown never ever work. Unemployment is high (though thanks to the way the government reports it the true rate is much higher than the official rate), and inflation is rampant (again the government misreports it). The nation is sick and falling apart like in 1860.
