A South Carolina pastor says he was not trying to be political when he posted a sign in front of his church linking Democratic presidential candidate Barack Obama and al-Qaida leader Osama bin Laden. Pastor Roger Byrd said he just wanted to make people think when he put up a sign reading "Obama, Osama _ humm, are they brothers" in front of the Jonesville Church of God on Thursday. Obama, a Christian, attends Trinity United Church of Christ in Chicago. Fifteen percent of respondents to a recent Associated Press-Yahoo News poll said they thought the Illinois senator was a Muslim. WYFF-TV reported Monday on its Web site that Byrd said he won't take the sign down. He said his congregation voted unanimously Sunday to keep it up.
