A slim majority of Americans think Congress should suspend work on healthcare until Democrats can attract more Republican support, according to a new USA Today/Gallup poll.

55% of respondents said lawmakers should stop work on the bill and consider alternatives. 39% say lawmakers should move ahead with the legislation.

The findings underscore the unsettled prospects for health care legislation — which has consumed much of the capital's attention for nearly a year — in the wake of Republican Scott Brown's upset victory in the Massachusetts Senate race Tuesday. When sworn in, he will give Republicans the 41st vote they need to sustain a filibuster and block action.

An overwhelming 72% of those surveyed say the Massachusetts result "reflects frustrations shared by many Americans, and the president and members of Congress should pay attention to it." Just 18% say it "reflects political conditions in Massachusetts and doesn't have a larger meaning for national politics."
