In my life when a white person leads off by saying something is not about race, it generally has been all about race. IMO the only reason people blame Obama for dividing America is that they need to blame somebody black in order to continue denying the real problem.
Obama was not divisive. TARP was a Bush policy. Obama didn't pit insurance companies or doctors against Americans. He didn't pit black against white. He didn't divide any more than any other president before him and in fact was better than Nixon, Ford, Carter, Reagan, both Bushes, Trump, and Clinton in that regard.
