A Texas congressman floated his own theory last night about the crisis of  illegal immigrants at his state’s border with Mexico. Speaking on “The O’Reilly Factor,” Rep. Louie Gohmert said he believes President Obama is encouraging Central Americans to cross into Texas because he wants them to stay and vote Democrat. “The president has said he is going to turn Texas blue,” Gohmert said. About one minute in, he and host Bill O’Reilly get into a passionate exchange.
