It looks like a representative of Obama’s campaign is getting closer to addressing students at Liberty University. John McCain’s brother, Joe spoke at convocation last month. Tuesday South Carolina Senator Lindsay Graham spoke on McCain’s behalf. Also Tuesday the director of Barack Obama’s Virginia office sent a letter to LU Chancellor Jerry Falwell, Jr. offering to have an Obama representative come speak. Falwell formally extended an invitation for a representative in the campaign to come speak. Now they’re working on the details on who will come and when, but it must be a national level spokesperson. By law, the school can keep its tax exempt status with political speakers, as long as both parties are asked.
