He also did NOTHING! He never particularly worked as a lawyer. As a political organizer he did nothing of significance. As an Illinois state senator he mostly voted "present" and submitted nothing of significance in the way of legislation. As a US senator, he put his name on a few bills others were primarily sponsoring and did nothing. As President he was mostly just there. He did nothing, nada, zip point shit.
Even with Obamacare, his contribution was signing the damned legislation. He had no role in crafting it and during debates with Republicans had his ass handed to him by policy and economic wonks that knew far more than he did about the bill.
I'll give Obama credit for being one of the slickest, most charismatic, politicians of all time. The guy could sell ice cubes to Eskimos. He was like Harold Hill in The Music Man. I'm not saying that's a bad thing for him. But it was a bad thing for the nation.
