Those of us from Jersey know that Chris Christie's plain-speaking rhetoric isn't his invention. That's that way we who had been born and reared in the Garden State framed our tone and word choice.
Christie's genius was to hone that into his signature style. He also made the strategic decision to marinate that in righteous anger. Voters, the media, and the powerful like Nancy Reagan liked what they heard. Christie leveraged that strategy well.
Now, with Bridgegate, that style may lose its ability to influence. According to the Rasmussen Reports survey, only 32% believe that Christie didn't know what his aides were up to in blocking most of the access from Fort Lee, New Jersey to the George Washington Bridge. Of course, this situation could morph into another Watergate.
Should Christie fall, his approach to rhetoric will go out of favor. Maybe Hillary Clinton always anticipated that. Her style has remained statesmanlike. We scriptwriters will get more requests for that. There could be zero requests for bluntness saturated with anger.
