ADVANCE FOR SUNDAY, DEC. 18 AND THEREAFTER - FILE - In this April 5, 1995 file photo, House Speaker Newt Gingrich of Ga. wears a 50-pound Binturong bearcat from Southeast Asia on his head on Capitol Hill in Washington. The speaker's office became a petting zoo as Columbus zoo director Jack Hanna paid a visit with a host of animals. 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.
