A top adviser to Herman Cain says the former presidential candidate plans to endorse one of his ex-rivals, most likely Newt Gingrich, this month in order to have an impact before the Iowa caucuses on Jan. 3.
“He wants to play ‘who to endorse’ for a while,” said the adviser, who spoke on condition of anonymity in order to speak bluntly. “Then he'll probably be endorsing somebody in a couple weeks — before the caucuses…. I'd say he's going to endorse Newt Gingrich,” the adviser said.
