Clinton’s survival ‘hangs on double-digit victory’

SIMPLE victory may not be enough for Hillary Clinton in tomorrow’s Pennsylvania Democratic primary, as Barack Obama tries yet again to kill off her never-say-die White House bid.

Many believe Clinton needs a double-digit triumph, in an economically struggling state packed with blue-collar voters who normally flock to her cause, to dispel the idea that Obama is becoming the inevitable nominee.

The former first lady, trailing Obama in nominating wins, delegates, and some national polls, needs to win big to freshen her rationale for staying in the protracted struggle for the nomination.
