I think he's sober and hardworking, perhaps too self-effacing for a national leader (he doesn't use the bully pulpit of the presidency as enthusiastically as he might); he got health reforms through, he hasn't conquered the global recession, but it took years to create so I wasn't expecting him to. I think the USA is in good hands.
There are however several billion other people on the planet, all real, who might conceivably disagree with me.
