Embattled White House hopeful Herman Cain effectively ended his presidential bid Saturday after support dried up in the wake of accusations from a string of women that he had engaged in sexual impropriety.Cain said he was technically "suspending" the campaign and vowed to press on with his unique blend of conservatism through a new website, thecainsolution.com."I am not going to be silenced and I am not going away," he said with his wife Gloria at his side, vowing to continue to be "a voice for the people."The announcement comes less than a week after a woman he characterized as a friend said she and the Georgia businessman had been carrying on a sexual affair for more than a decade. Ginger White said it was not a love affair, but Cain showered her with gifts and offered financial assistance for her monthly living expenses. Cain called the relationship a friendship as he acknowledged that his wife of more than four decades had no knowledge of White prior to Monday.Cain thanked his supporters for their support as he blamed the media for forcing his hand."I am disappointed that it came to this point, that we had to make this decision," Cain said."These false and untrue allegations continue to be spinned in the media, and in the court of public opinion so as to create a cloud of doubt over me and this campaign and my family. That spin hurts. It hurts my wife. It hurts my family. It hurts me. And it hurts the American people, because you are being denied solutions to our problems," Cain said.Full CBS News coverage of Herman Cain's campaignCain was already under pressure after revelations several other women had accused him of sexual harassment and inappropriate sexual advances in the 1990s while he was the head of the National Restaurant Association.The former CEO of Godfather's Pizza began his campaign in relative obscurity in May. He shot to the top of the polls in September on the strength of his personal charisma and the unexpected popularity among conservatives for his signature 9-9-9 tax plan to eliminate the current tax code in favor of a nine percent income tax, a nine percent corporate tax and nine percent sales tax.Cain said he was "at peace" with his decision."So one of declarations I want to make to you today is that I am at peace with my God. I am at peace with my wife, and she is at peace with me. And I am at peace with my family and at peace with myself," Cain said.Cain called at least some of Republican rivals before making the announcement.Former Massachusetts Gov. Mitt Romney said before the formal announcement that he wishes Cain well.
