Bill Clinton has risked inflaming the Democratic primary’s current debate over race, telling a rally in Tennessee that everyone has some African ancestry. Clinton’s comments came three weeks before the Tennessee primary, part of Super Tuesday on March first. In polls in the state, his wife holds a three-to-one lead over the Vermont senator Bernie Sanders. In 2008, she soundly defeated Barack Obama there. However, Tennessee also has a high number of undecided Democrats. Also, among registered voters Clinton’s negative ratings are the highest of all states. Democrats have warned that if she is the nominee she might drive a stronger turnout of Tennessee Republicans against her. In his Tennessee stump speeches, Clinton credited Obama for doing “a better job than he has gotten credit for”. But he also criticized him for failing to end Washington gridlock.
