Well me being the sceptic I am about Obama, I'm sure it's because Ohio is an important state in the elections. Everything he does is political. It's not the first time he has gone to Ohio to kiss-up to voters. He is always on the campaign trail. I haven't ever seen him do anything before that wasn't politically motivated, except go on vacation. Doing the right thing just for the sake of doing the right thing doesn't seem to me to be in his personality.
