New conservative groups launch ads
As polls indicate President Obama's is gaining the edge in key swing states, new Republican-leaning groups are entering the presidential advertising fray.
The commercials, aimed at voters who supported Obama in 2008 but are undecided now, join those from campaigns and outside groups swamping a narrow and possibly shrinking map of competitive states in the fast-moving presidential contest. The ads also focus on female voters, a bloc where Romney badly lags behind Obama. The group Americans for Job Security launched an ad in six swing states as part of an $8.7 million ad buy disclosed last week. Separately, a new conservative group bankrolled by billionaire Joe Ricketts, the Ending Spending Action Fund, is set to debut a $10 million, four-state ad campaign on Thursday.
