DES MOINES--Failed GOP White House hopeful Herman Cain, who dropped out after a woman who said she was his mistress went public is staging a comeback of sorts, he announced on Monday--on the eve of the Iowa caucus.

"Our mission continues, and we're on fire for 2012 and beyond!," Cain said in an e-mail, highlighting a list of media interviews he has booked. Cain is looking to regain some spotlight in a week heavy with Republican presidential politics--that he is no longer a part of.

"....I will soon be announcing a major new initiative. This is a crusade so critical to the long term health of our American economy that we simply must prevail. The first major announcement will be live on the Sean Hannity show, next Wednesday night between 9pm and 10pm ET," Cain said.
