By raising questions about Barack Obama's relationship with terror-bomber William Ayers, the Republicans are "sowing the seeds of hatred and division," Mr. Lewis said. "During another period, in the not-too-distant past, there was a governor of a state of Alabama named George Wallace who also became a presidential candidate. George Wallace never threw a bomb. He never fired a gun, but he created the climate and conditions that encouraged vicious attacks against innocent Americans who were simply trying to exercise their Constitutional rights. Because of this atmosphere of hate, four little girls were killed on Sunday morning when a church was bombed in Birmingham, Alabama."
