Herman Cain said Sunday that his national book tour — which some Republicans have argued could undermine his surging presidential campaign — will help his efforts, and that he plans to pick up the number of book-tour events.
"When I can meet [voters] at a book-signing and say hello to them, and they go home excited and they're talking with their friends and relatives, call them all across the country," Cain explained after a signing in Rock Hill, S.C. "So, no, I don't apologize for these kinds of events at all, and I'm doing more of them as part of the campaign."
Around 200 people attended the signing at a local Books-a-Million, according to NBC News. Cain appeared Friday at a Costco in Northern Virginia before attending the Values Voters Summit in Washington, D.C.
