Barack Obama may be like a rock star on his tour to become the US President, but it doesn’t shield him from the usual problems of a political campaign, like catching heat from lobby groups. A gay rights group is calling for a Gospel singer on Obama’s tour to leave the campaign after controversial comments about gay and lesbian people. Obama is actively trying to eradicate homophobia in conservative African-American communities, so to have an anti-gay Gospel singer on tour just seems counter-productive.
