(Black Politics On The Web) — President Barack Obama is a Christian who prays daily, a White House official said Thursday, trying to tamp down growing doubts about the president’s religion. A new poll showed that nearly one in five people, or 18 percent, believe Obama is Muslim. That was up from 11 percent who said so in March 2009. The survey also showed that just 34 percent said Obama is Christian, down from 48 percent who said so last year. The largest share of people, 43 percent, said they don’t know his religion.
