Buoyed by their weekend victory on a vote beginning the healthcare debate, several Senate Democrats expressed optimism they could find a way to keep a government-run insurance plan in the sweeping bill. The public insurance option in the Senate's healthcare overhaul is so modest that it "will, at the end of the day, be where we end up,'" predicted Senator Chuck Schumer, a New York Democrat who is working with moderates to find a compromise. He spoke on CBS's "Face the Nation.'" Democratic leaders need to win over a handful of skeptical Democrats and Republican moderates, as they did on Saturday night to proceed with debate, to get the required 60 votes to end the debate sometime in coming weeks and get to a vote on final passage.
