Most Americans don't expect healthcare overhaul to affect their lives directly, but those who worry about the fallout outnumber those expecting to come out ahead, according to a recent poll by the nonpartisan Robert Wood Johnson Foundation. The poll found that Americans are tuning in to the debate in Washington, with 60% saying they're following it very closely or fairly closely. Most see a change ahead for the nation, and they're divided on whether that will be for good or ill. But when it comes to their own personal lives, Americans say they don't expect much of an impact.
