Lets say that lieberman loses the primary and doesn't have enough signatures to get on the ballot as an idependent since those signatures are due the next day. How successful do you think a write-in campaign would be for lieberman? I'm betting he could walk away with 35-45% and win the election. I know a write-in campaign has only won a single U.S. Senate race, but this is a special circumstance.
He wouldn't win a write-in campaign, but it would make the race significantly closer. Lamont would still win, though.
