So watching it I can see how you find the imagery and message "interesting" as theyre are crazy pictures with "elites" drawn with devil horns and tails but look at the context. The song was released mid-2009 so Obama was currently president, the way in Iraq was getting bigger than ever and Obama was increasing troops and missle strikes. While the message is presented as coming together, he is still stuck in the same political division he is in today. Eminem and all others like him are still the swamp or "the mosh". When we realize that they are all in this together is when we can actually come together. I hate bush more than the next guy as well but understand the time this was released.

Also he uses coming together to get through the rain. Maybe the Storm/Rain is what needs to happen and he wants the sheep to join and fight against the storm. Everything can have double meaning
