The right to vote was passed and placed in the bill of rights (15th amendment) in 1870 part of the reconstruction era. So during 1960's during the civil rights movement the right to vote was not one of their goals because it was already in effect for African Americans to vote.
JFK was the first former scout to be President. Gerald Ford was the first and only Eagle Scout to be president. Bill Clinton and GW Bush were cub scouts. Since the inception of scouting in 1910 nearly all of the presidents have had some realtionship to scouting, often as adult leaders.
The story you heard yesterday about President Obama refusing to sign Eagle Scout Awards is true. He won't sign life saving awards either. Every President since 1912 has been the honorary President of the Boy Scouts of America. President Obama refused that honor.
