Republican presidential hopefuls Michele Bachmann and Herman Cain will appear in Rock Hill in separate events Friday.
Cain will hold a town hall forum at 1:30 p.m. at the Magnolia Room at Laurel Creek in Rock Hill.
Bachmann will appear at 3 p.m. Friday at the Manchester Village Books-A-Million in Rock Hill where she'll sign copies of her recently published memoir, "Core of Conviction: My Story."
The Minnesota congresswoman's memoir was released last week. Published by Sentinel, a conservative imprint within Penguin USA, the memoir recounts Bachmann's life from childhood growing up in Iowa and Minnesota, to pursuing college and a career as a tax attorney, business owner and politician.
Never miss a local story.
Bachmann told the Charlotte Observer on Tuesday that she hopes her book will help show voters that she will emerge as a conservative alternative to former Massachusetts Gov. Mitt Romney in the race to win the GOP nomination.
Her campaign is "poised to have the comeback," she said. "As we've seen, it's been up and down, up and down for the candidates. ... It's wide open."
After peaking at 14 percent in one South Carolina poll in August, Bachmann has dipped to below 4 percent, according to a state polling average by Real Clear Politics.
Former U.S. House Speaker Newt Gingrich of Georgia has surged ahead in recent South Carolina polls, but Bachmann said she doubts his record will stand up to the scrutiny of GOP primary voters.
Not only has he "established himself being for amnesty (for illegal immigrants) and on the side of global warming," she said, "he was grandfather of individual (health care) mandate.
"Our nominee can't hold those positions," she said.
Bachmann's book tour includes stops in Greenville later Friday, Aiken and Columbia on Saturday, and Myrtle Beach and Florence on Sunday.
Friday will make Bachmann's third visit to Rock Hill, following a June stop at Winthrop University for a town hall forum and a meeting with area pastors in August.
Cain also has made two stops in Rock Hill since announcing his candidacy. In September, he held a campaign event at Winthrop University, and in October he stopped at the Rock Hill Books-A-Million to sign copies of his recently released book, "This is Herman Cain! My Journey to the White House."
A Georgia native, the former Godfather's Pizza CEO is now a radio talk show host and business consultant. He has never served in public office but ran twice, in 2000 for Republican presidential nomination and in 2004 for the U.S. Senate in Georgia.
Cain enjoyed October and November leads in three South Carolina polls, but he now lingers in third place in the early primary state, trailing Gingrich and Romney, according to Real Clear Politics.
His campaign has been dogged by accusations of sexual harassment during the time when Cain was head of the National Restaurant Association.
Cain's most recent obstacle came this week, when a woman came forward claiming she was Cain's mistress for 13 years.
Cain denied the accusation but told his staff Tuesday that he was "reassessing" whether his campaign can survive them, or whether they will "create too much of a cloud, in some people's minds, as to whether or not they would be able to support us going forth," he said according to a transcript of a phone call to staff.
A campaign official said Tuesday that Cain is moving forward and doesn't plan to take time off. He plans to spend more time in South Carolina and other early primary states in coming weeks.
