Ever Heard of a Recess Appointment?

|
Bob Novak has a column in the W. Post (not yet posted, however) this morning about Chris Dodd's "clever" obfuscation over the Bolton nomination. It escapes me what's so clever about it. Isn't it predictable that the instant the Senate goes into recess, the Prez will just name him the interim ambassador --which would allow him to serve to the end of the Bush term? Can anyone come up with a reasonable explanation of why the Dems are going to the mat on this? They look like idiots.
