Hillary Rodham Clinton's role in formulating health-care reform may be controversial, but she's still planning to take a higher profile as the plan moves toward completion. The reason: Linking the proposal to the First Lady increases support among a key swing-voter group. Democratic pollster Celinda Lake focused on "cautious reformers"--the 15% to 18% of voters who favor change but worry that it will go too far and hurt the quality of care. Among this disparate group, ranging from union households to suburban Republican women, 53% favor "President Clinton's" health-care proposal. But when asked about a proposal drawn up by "President and Hillary Clinton," backing rises to 66%.
