Last voyage of the Pequod?

An anonymous White House advisor told CNN's Gloria Borger to think of President Obama's latest push to ram through a health care bill as

"the last helicopter out of Saigon."  

Last helicopter out of 'Nam?  I suspect for many of the Congressman the Democrats recruited in 2006 and 2008 this feels a lot more like the  last voyage of the Pequod .  I'm starting to think of him as President Ahab.
