Mark P. Jones, chairman of the political science department at Rice University, said Mr. Obama likely believes his time is better spent in battleground states and areas with strong concentrations of black voters instead of taking time to travel to red-state Texas to speak to a group that even some blacks have trouble embracing.
"The NAACP has some problems being relevant even among African-American voters," Mr. Jones said. "There's a substantial proportion that aren't entirely satisfied with the NAACP and don't view it as relevant as it was in the past. It's not an omnipotent organization. The president has far more support on his own than the NAACP. ... Even though he would like their support, he doesn't need it."
