Allegations that Barack Obama secretly practices Islam, or that he is the antichrist of Christian eschatology, or covertly holds some other esoteric religious position, have been suggested since he campaigned for the U.S. Senate in 2004 and proliferated after his election as President of the United States in 2008. As with conspiracy theories surrounding his citizenship status, the claims are promoted by various political opponents, with American bloggers and conservative talk radio hosts particularly promoting the theories.
