"Sen. Olympia Snowe (R-Maine), ...., told reporters Thursday that she would not vote to break a GOP filibuster if the bill put forth by Senate Majority Leader Harry Reid (D-Nev.) contains a public option."

So when "history calls" she'll summon up enough public spirit to help a weak bill out of committee, but when a more robust bill could come before the Senate for a floor vote, history doesn't call at all.
