Embattled Herman Cain suspended his GOP White House presidential campaign on Saturday, saying he is at "peace" with himself as allegations of a 13-year affair forced Cain to fold his bid.
With Cain out, the GOP contest seems headed to a showdown between Mitt Romney and Newt Gingrich.
"I am disappointed it came to this point, that I had to make this decision," Cain said in Atlanta, with his wife Gloria standing a few feet away.
Cain, a former CEO of Godfather Pizza, for a short time enjoyed a surge in the polls, only to start to fade when allegations of sexual harrassment surfaced from several women. While Cain thought he could weather that storm, the accusation of an affair was the last straw.
Running for president, Cain said, "is a dirty game." Cain said he move on to "Plan B," pushing for change as an outsider.
Cain denied any wrongdoing. He said he would be making an endorsement --and it would not be President Obama.
"Even though I have suspended my campaign, I have not given up on America," Cain said.
Suspending, rather than folding a campaign means a candidate can still raise and spend campaign donations.
