I noted with interest the other night on "Late Show With David Letterman," in a thinly veiled attempt to chide Mitt Romney, President Barack Obama said that as president he must represent all the people.

Was President Obama representing all the people when he called the Cambridge police stupid? Was he representing all the people when he called Republicans his enemies? Was he representing all the people when he said his son would look like Trayvon Martin, even before George Zimmerman was put on trial? Was he representing all the people when his vice-president said that Republicans wanted to put African-Americans back in chains? President Obama's entire re-election strategy is to divide and conquer. His chutzpah is breathtaking.
