Advisers to Obama and Clinton both told the party's platform meeting they were happy with the compromise, adopted without opposition or without explanation as to how health care would be guaranteed.

In return for the guarantee, activists dropped a tougher platform amendment seeking a government-run, single-payer system and another amendment explicitly holding out Clinton's plan as the one to follow.

The party now declares itself "united behind a commitment that every American man, woman and child be guaranteed to have affordable, comprehensive health care."
