Herman Cain, Sarah Palin at Liberty on Saturday

Another presidential candidate and one possible contender will be on the Liberty University campus this weekend.

GOP presidential candidate Herman Cain will do a book signing on Saturday, Oct. 8 at the Liberty University Barnes & Noble Bookstore. Cain, radio talk show host and former president and CEO of Godfather's Pizza, will be signing copies of “This is Herman Cain” from 11:30 a.m. until 1:30 p.m.

Former Alaska governor and 2008 vice presidential nominee Sarah Palin is scheduled to speak at the Extraordinary Women Conference on Saturday, Oct. 8 at Liberty’s Vines Center. The conference is not a public event and is not being sponsored by Liberty University.

“To have four declared or potential presidential candidates visit Liberty University in one semester is clear evidence of how Liberty has emerged as the preeminent Christian university in the nation. We are honored to have Sarah Palin and Herman Cain on campus,” said Chancellor and President Jerry Falwell, Jr.

Cain’s visit will mark the third 2012 presidential candidate on campus this year. Rick Perry spoke in Liberty’s convocation on Sept. 14. Michele Bachmann spoke on Sept. 28.
