But Cain's departure from the primary strikes a greater blow, as the former Godfather's Pizza CEO has been tied with Romney in the most recent spate of Republican national polls. Romney was counting on momentum from Nevada and New Hampshire to carry him in the South, where his opponents have been polling higher.
Romney said earlier today that he would not join a boycott of the Nevada caucus, and is headed there Monday to open his campaign headquarters. A CNN debate is scheduled for next Tuesday in Las Vegas, although some candidates have already indicated that they are considering boycotting that as well.
