political guru 

someone who knows exactly whats going on within the world of politics and politicians.

Ted: The election is coming up and I have no idea who's running for MP in my electorate! *panics* Do you have any idea who the Labor candidate is?

Greg: No idea, ask Wyman, he's a real political guru - he'll even be able to tell you what colour jocks each candidate is wearing.
