Organizing for Action, the nonprofit spinoff of President Obama's reelection campaign, is up with its second TV ad promoting Obama's signature health-care legislation.

The ad features the story of a girl named Zoe who had open-heart surgery as a newborn. It notes that Obamacare requires no lifetime limits for life-saving coverage and that without it, Zoe would already be halfway to her lifetime coverage maximum.

The ad is part of an OFA summer ad buy costing more than $1 million.

It comes just days after the Obama administration announced it would delay a major component of the health-care law -- the requirement that employers of a certain size provide health insurance options for their employees. The delay was seen as a significant setback for the divisive law.
