Democrat Sam Nunn: The former senator, 69, a defense expert, has advised Obama on nuclear issues and could help carry his native Georgia and other states in the South. But hes been retired from electoral politics for more than a decade, and many gay Democrats oppose him because he helped block President Clintons proposal in 1993 to allow gays to serve openly in the military. Dick Morris, a former advisor to President Clinton, has said that Nunn would be for Obama what Vice President Dick Cheney was for President Bush - an elder statesman. Its a compliment that may not impress many Democrats.
