Those who wish Obama would use the Jeremiah Wright controversy to reaffirm the "unity" rhetoric are in luck: He'll be making a "major address" at 10:15 a.m. tomorrow in Philadelphia on "race, politics, and unifying our country." I'm expecting the speech to talk about overcoming the divisive racial politics of the past while continuing to be inspired by the Civil Rights movement and other social justice struggles. Guess we'll find out tomorrow. --Dana Goldstein
