I think it was an instructive moment for democrats. Landreau was sacrificed by her own. The message was.....get in line and stay in line or the same will happen to you. They are all in for Obama, regardless of how counterintuitive it for the benefit of the country. Message sent....message received by all dems. They do not have the stones to stand up for the people who put them in office. It should be clear that that the people want this pipeline by a 4: 1 margin. But their retort is screw the public and their jobs.
We will see if the republicans heard the public.
