Summer blitz: GOP outside groups spending more than $19 million on anti-Obama ads this week

— -- It's the first day of summer, and if you plan to beat the heat by kicking back in front of the tube, prepare for an onslaught of political ads against President Barack Obama, none of which will be paid for by Mitt Romney's presidential campaign.

Three outside groups are independently launching multimillion ad campaigns  that will run over the next ten days in battleground states across the country. The organizations, Restore Our Future, Concerned Women for America (CWA) and Americans for Prosperity (AFP), plan to spend a combined $19.1 million on the three ads.

Restore Our Future, the primary super PAC supporting Romney's campaign, is launching the largest blitz with an eight-state, $7.6 million air-time buy. The ad knocks Obama for saying during a recent press conference that the "private sector is doing fine," and focuses on unemployment. The Americans for Prosperity spot--which shares the same title, "Doing Fine,"--also uses the Obama sound bite and a similar argument. Concerned Women for America's ad takes a different approach, focusing on health care policy. Their ad will run during the period in which the Supreme Court is expected to announce its decision about the constitutionality of the president's health care law.

The ads for two of the groups, CWA and AFP, are being paid for through the organizations' 501(c)4 non-profit arms, which are not required to release the names of their donors. Restore Our Future, a so-called super PAC that can directly advocate for a candidate, must disclose.
