Romney had no public appearances scheduled Tuesday and planned to raise money in Salt Lake City and in Dallas with former first lady Laura Bush at the Bushes' Texas home.
Looking to change the subject, Romney's campaign rolled out a new television ad featuring a mother and infant, aimed at cutting into Obama's advantage with female voters. It argued that Obama's economic policies would make women's lives harder.
In the video, Romney said 47 percent of Americans pay no income tax. About 46 percent of Americans owed no federal income tax in 2011, although many of them paid other forms of taxes. More than 16 million elderly Americans avoid federal income taxes solely because of tax breaks that apply only to seniors, according to the nonpartisan Tax Policy Center.
In the clip released by Mother Jones, Romney also is asked about the "Palestinian problem." He gives a rambling response, then says "the Palestinians have no interest whatsoever in establishing peace" and "the pathway to peace is almost unthinkable to accomplish."
