President Barack Obama on Thursday flipped into campaign mode and dared Republicans to repeal the healthcare law. With his signature agenda item signed into law, Obama switched from selling the bill to aggressively promoting it during a speech in Iowa City, Iowa, the town where Obama announced his healthcare reform agenda as a candidate in 2007. “This is the reform that some folks in Washington are still hollering about. And now that it’s passed, they’re already promising to repeal it,” Obama said. “They’re actually going to run on a platform of repeal in November. Well I say go for it.”
