 From November 2007 to January 2008, as part of a drive to promote awareness of his Christian faith, Obama gave interviews to Pat Robertson's Christian Broadcasting Network, to "Christianity Today" and to the religious website Beliefnet.com.Nevertheless, the false belief that Obama is a Muslim has persisted in some key demographics and is among the most frequently cited reasons for opposition to Obama in public polling.In polls taken in March and April 2008, between 10 and 15 percent of respondents believed Obama was Muslim.
