Could you give an example where Obama pushes a left policy that's more left than Merkel's position on the same issue?
It depends when in time you compare them. Merkel did come out against a federal minimum wage at one point (during the election). IMO, that is more "right-wing" in the sense people usually mean by it (although I don't particularly like the term). As far as I know, Obama has never publicly criticized the federal minimum wage.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Of course, for "every Monday", the last one should have been dated July 22-28. *cough*
