Gov. Chris Christie is continuing to use his public appearances to single out someone for his biting brand of criticism.

This week at a town hall meeting, he attacked Democratic Assemblyman Lou Greenwald. He said Greenwald and other Democratic members of the Assembly are the only people blocking tax cuts and are full of "stupid ideas."

At other appearances he has called a budget analyst the "Dr. Kevorkian of the numbers" and said it's time for 88-year-old U.S. Sen. Frank Lautenberg to retire.

Montclair State political scientist Brigid Harrison says creating "demons" makes his constituents feel like they're part of a movement.

Some of the enemies he identifies fight back. Just before Christie spoke in Haddonfield this week, Greenwald put out a pre-emptive statement criticizing the governor and his policies.
