It means something like "Every man for himself."

Then I heard an all-hands call on my helmet that I never want to hear again. “Sauve qui peut! Home! Home! Pickup and home! Any beacon that you can hear. Six minutes! All hands, save yourselves, pick up your mates. Home on any beacon! *Sauve qui – *

Democrats on Capitol Hill fear Obama fallout

By Andrew Ward in Washington

Democratic jitters about the US presidential race have spread to Capitol Hill, where some members of Congress are worried that Barack Obama’s faltering campaign could hurt their chances of re-election.

Party leaders have been hoping to strengthen Democratic control of the House and Senate in November, but John McCain’s jump in the polls has stoked fears of a Republican resurgence.

A Democratic fundraiser for Congressional candidates said some planned to distance themselves from Mr Obama and not attack Mr McCain.

No reason at all.
