ADVANCE FOR SUNDAY, DEC. 18 AND THEREAFTER - FILE - In this Jan. 26, 1984 black-and-white file photo, Rep. Newt Gingrich, R-Ga. laughs at a joke told by President Ronald Reagan in Atlanta. Risen improbably from the ranks of GOP presidential discards, Gingrich is holding forth in Iowa, New Hampshire, South Carolina and beyond, lobbing rhetorical grenades that delight Republican voters hungry for someone with more moxie than Mitt Romney.
