Duluth, Ga.

SITTING in the back seat of his mother’s van as she drives through Atlanta suburbs, Jonathan Krohn is about to sign off with a conservative radio talk show host in Florida. In the 40 minutes he’s been on the air, with the help of his mother’s cellphone, this hyper-articulate Georgia eighth grader has attacked the stimulus bill, identified leaders he thinks will salvage the Republican Party’s image, and assessed the legitimacy of Barack Obama’s birth certificate.

The show’s host chuckles and asks whether President Obama has called Jonathan “a little fascist.”

“The president hasn’t come after me yet,” Jonathan says chummily, “but we’ve had other people come after me!”

“Jonathan!” his mother hisses from the driver’s seat.

The interview concluded, Jonathan wistfully handed his mother her cellphone. His parents still won’t let him have one, even though he turned 14 last Sunday, right after he became an instant news media darling and the conservative movement’s underage graybeard at last weekend’s Conservative Political Action Conference in Washington.

The annual convention brings in the movement’s grand old lions, like Rush Limbaugh, as well as cubs to rally 8,500 of the faithful, who were shaken by the election of Barack Obama. Jonathan, a slight, home-schooled only child whose teeth are in braces, is so passionate about his beliefs that he spent his summer writing “Define Conservatism,” an 86-page book outlining what he says are its core values. In January, he contacted CPAC organizers, asking to speak there.
