For the first time since the Gallup organization began asking the question in 1995, more Americans describe themselves as "pro-life" than "pro-choice." In its annual survey of values and beliefs, 51 percent said that they are "pro-life" when it comes to abortion, while 42 percent called themselves "pro-life," accounting for a sampling error of plus or minus 3 percentage points. In its analysis, Gallup said that it is possible that President Obama "has pushed the public's understanding of what it means to be 'pro-choice' slightly to the left, politically." Larry Mantle talks with guests about the poll and what the numbers mean.
