Why Are Americans Changing Their Mind on Gay Marriage?

Since 1996, Gallup has been polling Americans about gay marriage. In the past, the majority of their respondents were opposed to it being legally recognized. But last month, for the first time, the majority of respondents said they were in favor of gay marriage being legalized. Why are Americans changing their minds? Last year,  Louis Marinelli  helped organize the 2010 Summer for Marriage Tour which stood in opposition to gay marriage. This year, Louis is leading the Summer for Marriage Equality Tour. Jeff Angelo  also joins us. A former Iowa State Senator and Republican, he used to be opposed to gay marriage, but has since founded Iowa Republicans for Freedom, an organization that supports marriage equality.
