The shrewd politico that he is, Chris Christie dropped the brash tone in presenting the proposal for the state budget to the Legislature. Here is the coverage of that in The Wall Street Journal (sub. req.) Such bravado would have made his come across as cartoonish post-Bridgegate. His new persona had to be more statesmanlike. And that might just get him to the White House.
Aside from the New York Metro area, pockets of high-tech and games among five-year-olds brash doesn't play well in America. It not only drains the audience. It seems disrespectful. After her healthcare reform initiative blew up during her husband's first term as president, Hillary Clinton adopted a measured approach to public speaking. Forever cautious, she does allow her high intelligence to come through.
What the new Christie will let come through is his determination to make government more efficient. We could go for that.
