Even politicizing the State Department. ThinkProgress shows how the State Department pressed a narrow interpretation of Department guidelines in restricting Foreign Service Officers in Berlin from any involvement in Sen. Obama's visit to Germany (which I actually think was a good idea). But just last month Sen. McCain gave a political speech in Canada which was both attended by and arranged by the US Ambassador. Give it a read.

Late Update: And it seems McCain got the Foreign Service treatment in Mexico City too.
