I guess I understand why Barack Obama doesn't do more news conferences. There's really not a whole lot of upside for him; he's probably better off doing sit-down interviews with people who can be counted on to lob softballs. And it's not as if he has difficulties finding a way to say something on the record that he wants to say. Moreover, the press seems to have given up on what they used to do back during the Nixon and Reagan administrations, non-stop complaining designed to bully the president into it.
Still, I wish he would do it more regularly. This was (according to CNN at least) the first one in three months, and I'd much rather see a couple of them a month. I don't have any illusions about how press conferences "force" the president to talk about things -- no one reaches that stage of politics without learning the technique of dodging questions. But this is one that I do have a bit of idealism about; I think it's healthy for the democracy for the president to go through the process, no matter how limited it is.
So good for Obama for doing it today (and he did fine; he's pretty good at the format now), but I'm hoping to see another one soon.
