White House works to shape debate over health law

The White House has begun an aggressive campaign to use approaching Supreme Court arguments on the new healthcare law as a moment to build support for the measure seen as President Obama's signature legislative achievement, hoping to shape public opinion on an issue at the center of the battle for the White House and Congress. The advocates and officials mapped out a strategy to call attention to tangible benefits of the law, like increased insurance coverage for young adults. Sensitive to the idea that they were encouraging demonstrations, White House officials denied that they were trying to gin up support by encouraging rallies outside the Supreme Court.
