He rescued the economy after the biggest financial ruin the country had seen since the Great Depression.
He expanded the parameters around eligibility for Medicaid, making health care much more accessible to a larger demographic.
One of the biggest traits the 44th U.S. president says he inherited from his grandparents was their work ethic.

Obama’s grandfather died in 1992, just three years before his mother lost her battle to cancer.
Their heavy drinking after work reminded Obama of the characters in the hit TV drama “Mad Men.”
“It explains my grandparents, their tastes,” he told Maraniss (viaAssociated Press).

Nonetheless, he admired his grandparents greatly, keeping their values close to his heart during his presidency.
Humility; responsibility; helping each other out."
Those are the qualities Obama says he teaches his own children.
