President Obama had a great record and had campaigned as a progressive.
He had no record and campaigned as "Hey, I'm Black."
President Obama was not under any investigations of any kind, especially FBI investigations.
Never having done anything in your whole life can be and advantage after all.
President Obama was against the Iraq war
Which was effectively over when he took office, then he proceeded to screw the pooch on it so bad it came back to life while he was still in office. He was FOR the Afghan war, which he also hosed up royally, then started a war for NOTHING in Libya and turned a stable state into a terrorist cesspool, and managed to destabilize the entire African Med littoral and Syria at the same time, achieving NOTHING which was good for the US or US interests in the region, and that in turn further screwed up Iraq. And don't even get me started on what he did with Iran.
President Obama campaigned for peace
Well, he got a Nobel Peace Prize, anyway.
