Mitt Romney is trying to shift the national focus back to the economy by shrugging off discussions of gay rights after President Obama's historic endorsement of same-sex marriage Wednesday. His schedule is making that tough, since on Friday he heads to North Carolina, the state that just approved a ban on same-sex unions. He'll also give a commencement address Saturday at Liberty University, the Virginia school founded by the late Rev. Jerry Falwell, who vehemently opposed gay rights.
