Herman’s campaign has faced a number of allegations that he sexually harassed female employees and this week was almost destroyed after an Atlanta woman announced that she and Cain had a 13-year affair.
“I am reassessing because of all this media firestorm stuff,” Cain told his followers in South Carolina. “Why? Because my wife and family come first. I’ve got to take that into consideration.”
The former pizza’s Godfather added he intended to make a “major announcement” on whether or not he would continue presidential run.
“Tomorrow in Atlanta I will be making an announcement but nobody is going to get me to make that prematurely,” Mr Cain said.
“That’s all there is to that. Tomorrow we’re going to be opening our headquarters in Northwest Georgia. We will clarify, there’s that word again, clarify what the next steps are.”
The candidate received 8 percent support among Republicans in Iowa, which holds the first U.S. nominating contest of the 2012 election cycle on January 3.
“The writing’s on the wall,” said Republican strategist Ron Bonjean. “The polling has dropped to the floor. He can no longer sustain a positive campaign with these allegations.”
Cain is expected to meet with supporters in Atlanta who to gather for the opening of his Georgia campaign headquarters scheduled 11 a.m. EST/1600 GMT, and to look at what happens to his campaign contributions.
“We have got to re-evaluate the whole strategy. Tomorrow in Atlanta, I will be making an announcement, but nobody’s going to get me to make that prematurely,” Mr Cain said.
A source which is close to the campaign revealed that it Cain’s decision remains unclear what. “It could be the grand closing as well as the grand opening,” the source said.
Cain’s supporter, Doug Westmoreland of Clover, South Carolina, said wish the Cain campaign didn’t end. “I think I live in a country where you are innocent until proven guilty,” he said.
Four days has passed since White,45, made her allegations, but still no firm evidence has emerged to back up her story.
She announced that for more than a decade, Mr Cain flew her around the country for sex in upmarket hotels: “It was a sexual affair, as hard as that is for me to say and as hard as it is for people to hear it. You know, it pretty much is what it is. And that’s what it was,” the woman said.
“My wife and I have talked about it and I have explained it to her. My wife understands that I’m a soft-hearted giving person,” he said.
However, White said her sorry to Cain’s wife:
“My heart bleeds for this woman because I am a woman and being in a situation like this cannot be fun,” she said. “And I am deeply, deeply sorry if I have caused any hurt to her and to his kids, to his family. That was not my intention.”
The candidate, who led the Republican race about a month ago, has also become a victim of several self-inflicted stumbles.
Newt Gingrich, the former Speaker of the House who is not at the top, according to the polls, is likely to get lots of benefit in case Cain does drop out of the presidential race.
