Republicans are struggling with renewing their effort to overturn health-care legislation, a goal that has caused deep division at a time when lawmakers are promising renewed unity. The House vote to repeal the law was put on hold this week after the shooting in Arizona. If Republicans return to it too quickly, they could appear tone deaf. If they wait too long, they will anger conservative supporters. Republicans are expected to announce Thursday when the vote will take place. Said one Tea Party leader about the delay, "This is not the serious getting-down-to-business in Congress that people voted for. I think it's a mistake. It shows a sort of lack of spine and will and it's disappointing."
