Taqiyya (al-Taqiyya) is a concept in Shia Islam the encourages "disguising one's beliefs, intentions, convictions, ideas, feelings, opinions or strategies." It is authorized under the Qur'an and Sunna.[Citation Needed]
Taqiyya further permits "lying under oath in testimony before a court, deceiving by making distorted statements to the media such as the claim that Islam is a 'religion of peace.'"
Many people believe that Barack Obama is a Muslim using Taqiyya as a means to justify to himself publicly denying his faith. A survey in March 2008 by the Pew Research Center for the People & the Press found that ten percent of American voters believe Sen. Barack Obama is Muslim. 16% of conservative Republicans, 16% of white evangelical Protestants and 19% of rural Americans believe the Illinois senator is Muslim.  In a later survey, in July 2008, the number had risen to 12% of American voters who think Obama is a Muslim. Interestingly, 37% of those who think he's Muslim intend to vote for him.
