I don't think it's wrong at all. In fact, it's kind of impossible not to like Obama, the way he is pictured by most people is of this bad-ass president person, even if he has not been perfect. On the other hand, the Mexican president as a figure (let alone him being Felipe Calderón) has always been mocked, ridiculed, and hated for the state of the country and the economy. A Mexican president has never been portrayed as cool, hip, or someone to look up to; it's only natural that we don't love him.
