Sure, some do.
If you want to provide examples of Obama "race baiting," go ahead. I don't think you actually have any.
What you WILL find is him opening some of those boxes that white people would rather leave closed.
Yes, they were challenging. I think they've changed their brand lately. They're much better than they were.
