The public's views on healthcare have stayed largely steady this year, despite dramatic swings in the political battle over President Barack Obama's drive to revamp the nation's medical system, a survey says. Overall, 82% say an overhaul of the nation's healthcare system is important for recharging the economy, according to an average of monthly polls conducted since April by the nonpartisan Robert Wood Johnson Foundation. The most recent survey, covering November, found that 77% agree with that connection. Personal concerns have remained fairly constant as well. About one in four people worry they might lose their health coverage in the next year, while almost half say they are concerned they might not be able to afford care for themselves or a relative.
