Barack Obama should be congratulated on winning the Democratic Party nomination for the US presidency.
It's not only about Obama making history by becoming the first black Democrat nominee for the presidency. The litmus test will be the legacy he leaves behind if he is elected on November 4 to lead that country.
Obama has an opportunity to change the world by becoming the first president since JF Kennedy to end the economic blockade of Cuba that started in 1962. The blockade has crippled Cuba's economy and caused immense suffering among the people of this tiny island.
