Same.
Not so many for Obama and to be honest I don't remember Obama promising world domination or Garrosh promising socialised medical care. Which kind of shows how less alike to Garrosh he is. Since, you know, Garrosh kind of did his part about trying for world domination military speaking, assuring lands for orcs and resources so they don't need to live in deserts anymore, putting orcs in power of the Horde. Plus, Garrosh is a mongrel that attacks everyone who disagrees with him. So this means in the end, your only argument that remains is that Garrosh is Obama because they're both brown. By that same argument I could also say Garrosh is ... 50 cent. They're also brown and 50 cent sometimes also shaves his head, just like Garrosh.
