How long will the media keep pushing the"Hapless Democrats" narrative?

Kevin Drum asks when the media will catch up to the real story. The media keeps stating that the Democrats are disunited and unable to do anything in Congress, but look at the last year:

Consider. Democrats successfully killed a Social Security privatization plan that nearly everyone thought was a lock for passage. Harry Reid forced the Intelligence Committee to investigate prewar intelligence by shutting down the Senate. Nancy Pelosi worked shrewdly with Jack Murtha to give him the maximum possible attention for his pro-withdrawal message. (Yes, really.) George Miller single-handedly forced George Bush to rescind his suspension of the Davis-Bacon Act following Hurricane Katrina. And Chuck Schumer was the driving force behind criticism of the Dubai port deal.

These are real successes, not given to a party that is timid and disunited. So when does the media wake up and abandon that storyline?
