A new NBC/WSJ poll shows President Barack Obama's healthcare law remains unpopular with the American public with 44 percent calling it a bad idea and 31 percent believing it's a good idea, virtually unchanged from July's survey. In addition, by a 45 percent to 23 percent margin, Americans think the law will have a negative impact on the country's healthcare system rather than a positive one. And 30 percent of respondents think it will have a negative impact on their families. Only 12 percent say it will be positive, and a majority--53 percent--don't believe the law will have an impact one way or another. Poll results
