Mr. Obama has a tendency to overintellectualize and to lecture, befitting his training as a lawyer and law professor. He exudes disdain for the quips and sound bites that some deride as trivializing political debates but that have become a central part of scoring them. He tends to the earnest and humorless when audiences seem to crave passion and personality. He frequently rises above the mire of political combat when the battle calls for engagement.
Broder's mistake is that he thinks Obama can be coached out of these problems. He, like most Obama fans, ignores the fact that Obama was not raised with ordinary Americans. And Obama, after his rather unconventional childhood, studied in a cosmopolitan university. That's not a sin, but it does make it difficult for him to relate to ordinary Americans. This has nothing to do with Obama's skin color.
