Which Newt Gingrich will voters see? (Charles Krupa/Associated Press)

First, our colleague Amy Gardner reports on the “tale of two Newts,” the game that watchers of the campaign of former House Speaker Newt Gingrich are playing. Will they meet “Nice Newt,” who plays well with others, or “Nasty Newt, who calls rivals liars, snarls, and generally acts unpleasant?”

And our colleague Chris Cillizza explores Mitt Romney’s Hulk-like transformation when faced with confrontational hecklers, rivals or questioners. Okay, so the former Massachusetts governor doesn’t turn into a giant green monster and throw cars around, but he does exhibit testiness that makes him look “less than presidential,” Cillizza says.

Not that voters are that well-behaved, either: Our colleague Joel Achenbach reports on the mood in New Hampshire — and it isn’t so civil. “This has been the year of the shouter, the provocateur, the heckler,” he notes.

Elsewhere, the Reliable Source reports on a phenomenon that might soon turn into a full-blown trend: Celebrities’ kids joining the federal workforce. This time, it’s Oprah bestie Gayle King’s daughter, Kirby Bumpus, going to work for HHS.

Previously, the Reliable Source reported that Ronan Farrow, son of Mia Farrow and Woody Allen, has been toiling away at the State Department.

Which celebu-kid is next?
