Organizing for Action, the spinoff of President Obama's 2012 reelection campaign, is out with its first ad, in which it offers the president some backup on his health-care law.

The ad, titled "Impact of Obamacare," offers anecdotal evidence of the program's benefits.

"Better coverage and lower costs; that's what Obamacare means for them," the narrator says.

The ad is part of a seven-figure summer ad buy focusing on Obamacare.

The implementation of the law has started to cause some headaches for the administration, with even some top Democrats worrying about it. Senate Finance Committee Chairman Max Baucus (D-Mont.) recently worried aloud that the implementation would constitute a "huge train wreck," with people unsure about how to navigate the new law.

Recent polling has shown that more Americans dislike the law than favor it. An NBC News/Wall Street Journal poll in recent weeks showed 49 percent oppose it, while 37 percent support it — a new high for opposition to the law. Other polls have shown a closer split.
