Meet the man with the mustache who takes a drag on a cigarette in the Herman Cain Internet ad gone viral.
He's Mark Block, Cain's unorthodox campaign manager. Perhaps no one is more responsible for the Georgia businessman's meteoric rise in the presidential polls than Block, a Republican strategist and tea party leader who's left a trail of questionable campaign work behind him.
Block has been accused of voter suppression and was banned from running Wisconsin political campaigns for three years to settle accusations he coordinated a judge's re-election campaign with a special interest group.
Records show Block has faced foreclosure. He also acknowledges he was arrested twice for drunken driving.
He denies any wrongdoing and says he faced a tough time after he was banned from political work.
