Problem: Background: Kwame Nkrumah PC (21 September 1909 - 27 April 1972) was a Ghanaian politician and revolutionary. He was the first prime minister and president of Ghana, having led it to independence from Britain in 1957. An influential advocate of Pan-Africanism, Nkrumah was a founding member of the Organization of African Unity and winner of the Lenin Peace Prize in 1962. After twelve years abroad pursuing higher education, developing his political philosophy, and organizing with other diasporic pan-Africanists, Nkrumah returned to Gold Coast to begin his political career as an advocate of national independence.
Context: Beginning in April 1949, there was considerable pressure on Nkrumah from his supporters to leave the UGCC and form his own party. On 12 June 1949, he announced the formation of the Convention People's Party (CPP), with the word "convention" chosen, according to Nkrumah, "to carry the masses with us." There were attempts to heal the breach with the UGCC; at one July meeting, it was agreed to reinstate Nkrumah as secretary and disband the CPP. But Nkrumah's supporters would not have it, and persuaded him to refuse the offer and remain at their head.  The CPP adopted the red cockerel as its symbol - a familiar icon for local ethnic groups, and a symbol of leadership, alertness, and masculinity. Party symbols and colours (red, white, and green) appeared on clothing, flags, vehicles, and houses. CPP operatives drove red-white-and-green vans across the country, playing music and rallying public support for the party and especially for Nkrumah. These efforts were wildly successful, especially because previous political efforts in the Gold Coast had focused exclusively on the urban intelligentsia.  The British convened a selected commission of middle-class Africans, including all of the Big Six except Nkrumah, to draft a new constitution that would give Ghana more self-government. Nkrumah saw, even before the commission reported, that its recommendations would fall short of full dominion status, and began to organise a Positive Action campaign. Nkrumah demanded a constituent assembly to write a constitution. When the governor, Charles Arden-Clarke, would not commit to this, Nkrumah called for Positive Action, with the unions beginning a general strike to begin on 8 January 1950. The strike quickly led to violence, and Nkrumah and other CPP leaders were arrested on 22 January, and the Evening News was banned. Nkrumah was sentenced to a total of three years in prison, and he was incarcerated with common criminals in Accra's Fort James.  Nkrumah's assistant, Komla Agbeli Gbedemah, ran the CPP in his absence; the imprisoned leader was able to influence events through smuggled notes written on toilet paper. The British prepared for an election for the Gold Coast under their new constitution, and Nkrumah insisted that the CPP contest all seats. The situation had become calmer once Nkrumah was arrested, and the CPP and the British worked together to prepare electoral rolls. Nkrumah stood, from prison, for a directly-elected Accra seat. Gbedemah worked to set up a nationwide campaign organisation, using vans with loudspeakers to blare the party's message. The UGCC failed to set up a nationwide structure, and proved unable to take advantage of the fact that many of its opponents were in prison.  In the February 1951 legislative election, the first general election to be held under universal franchise in colonial Africa, the CPP was elected in a landslide. The CPP secured 34 of the 38 seats contested on a party basis, with Nkrumah elected for his Accra constituency. The UGCC won three seats, and one was taken by an independent. Arden-Clarke saw that the only alternative to Nkrumah's freedom was the end of the constitutional experiment. Nkrumah was released from prison on 12 February, receiving a rapturous reception from his followers. The following day, Arden-Clarke sent for him and asked him to form a government.

Problem: Background: Michael Bloomberg was born at St. Elizabeth's Hospital, in the Brighton neighborhood of Boston, on February 14, 1942. Bloomberg's family is Jewish. Bloomberg's father, William Henry Bloomberg (1906-1963), was born in Chelsea, Massachusetts and worked as an accountant for a dairy company. He was the son of Alexander "Elick" Bloomberg, an immigrant from Russia.
Context: In March 2010, Bloomberg's top political strategist Kevin Sheekey resigned from his mayoral advisory position and returned to Bloomberg LP, Bloomberg's company. It was speculated that the move would allow Sheekey to begin preliminary efforts for a Bloomberg presidential campaign in the 2012 election. An individual close to Bloomberg said, "the idea of continuing onward is not far from his [Bloomberg's] mind".  In October 2010, The Committee to Draft Michael Bloomberg - which had attempted to recruit Bloomberg to run for the presidency in 2008 - announced it was relaunching its effort to persuade Bloomberg to wage a presidential campaign in 2012. The committee members insisted that they would persist in the effort in spite of Bloomberg's repeated denials of interest in seeking the presidency.  While on the December 12, 2010, episode of Meet the Press, Bloomberg ruled out a run for the presidency in 2012, stating: "I'm not going to run for president," further adding "I'm not looking at the possibility of running ... no way, no how." On July 24, 2011, in the midst of Democrats' and Republicans' inability to agree on a budget plan and thus an increase in the federal debt limit, the Washington Post published a blog post about groups organizing third party approaches. It focused on Bloomberg as the best hope for a serious third-party presidential candidacy in 2012.  During an appearance on The Daily Show in June 2012, London Mayor Boris Johnson told host Jon Stewart that he did not know why Bloomberg had ruled out a bid for the presidency in the upcoming election, declaring that he would be "a great candidate".  Bloomberg had privately indicated he believed Mitt Romney would be better at running the country, but could not publicly support him because of Romney's positions on social issues such as abortion and gun control. In the immediate aftermath of Hurricane Sandy in November 2012, Bloomberg penned an op-ed officially endorsing Barack Obama for president, citing Obama's policies on climate change.
