Singer Paul Hipp is making his own contribution to the health care discussion with his catchy video "We're No. 37," highlighting the World Health Organization's ranking of the United States as 37th among health systems. The Web site PolitiFact.com noted that other WHO rankings have put the U.S. system in 15th place and first place (the latter for responsiveness). "Still, this is a rock song, and a well-sourced one at that. So we find Hipp's claim to be Mostly True," the fact-checkers declared.
