According to Gallup, Obama left office with a 59 percent approval rating, and George W. Bush 34 percent. I'm not sure if you would care to suggest some alternative facts, but if we can get past the point of agreeing on approval ratings, I would love to discuss your definition of a failed presidency.
Some common definitions:
1) Failed to win re-election. Nope. Won both the electoral and the actual popular vote, meaning, unlike Donald Trump, a majority of actual voters voted for Barack Obama than voted for his opponent.
2) Left the country in financial ruin:
Nope. His policies, though imperfect, averted the next Great Depression. Unemployment, auto market, housing market, stock market, all point to a successful presidency. Again, you have to decide whether to trust the official numbers or not. For me, being a blue collar type with a wife and a child, my financial opportunities improved exponentially.
3) Didn't have a magic wand. Got me there. Slow and steady improvement over the last eight years instead of a majestic (but perhaps unsustainable) burst left a lot of people unimpressed.
But at the end of the day, my friend, I can't claim to be truly objective and, no offense, neither can you. People aren't built that way. At the end of the day, I still love the meme showing a toddler in a high chair and says: "Once you hate someone, everything they do is offensive. Look at that bitch eating those crackers like she owns the place."
