It really does seem like that giddy, school-girl crush feeling that American liberals felt for Barack Obama is beginning to turn. Here, for example is Richard Cohen in the Washington Post (yes, that Richard Cohen and that Washington Post) --
Sooner or later it is going to occur to Barack Obama that he is the president of the United States. As of yet, though, he does not act that way, appearing promiscuously on television and granting interviews like the presidential candidate he no longer is. The election has been held, but the campaign goes on and on. The candidate has yet to become commander in chief...
Obama lost credibility with his deadline-that-never-was, and now he threatens to lose some more with his posturing toward Iran. He has gotten into a demeaning dialogue with Ahmadinejad, an accomplished liar. (The next day, the Iranian used a news conference to counter Obama and, days later, Iran tested some intermediate-range missiles.) Obama is our version of a Supreme Leader, not given to making idle threats, setting idle deadlines, reversing course on momentous issues, creating a TV crisis where none existed or, unbelievably, pitching Chicago for the 2016 Olympics. Obama's the president. Time he understood that.
