What "big data" elements were used in Obama's campaign in 2008?

Bama’s speech was not only passionate and inspiring, but also concise and concise with a prominent theme. This kind of speaking skill that combines preacher and salesman can produce star effect after being amplified by the media. Obama was successfully elected as the 44th President of the United States and the first black president in American history. A new generation of change in America is coming. Are Obama's "changes" the beginning of another "Roosevelt New Deal"? Although the financial and economic crisis faced by Obama when he came to power cannot be compared in degree to that when Roosevelt came to power, it was the most serious crisis faced by any president after Roosevelt. The financial crisis triggered by the subprime mortgage crisis has destroyed the wealth accumulated by many American families over the past decade. Whether the market can be stabilized and investor confidence can be stabilized as soon as possible will determine whether Obama will become a national hero like Roosevelt, or a flash in the pan. Black president. At noon on November 5, 2008, the United States made a great decision. For the first time in history, a dark-skinned man took control of the top of power in the world. Only 12 years ago, he was just a civilian; four years ago, his position was equivalent to that of an ordinary provincial people's congress representative in China. Obama, who only entered the political arena at the age of 35, has no prominent background, no cordial care from leaders at all levels, and has not even received years of training and testing from the grassroots level. What made him rise so quickly? 1. Obama in the party primary election Announcement of Candidacy Barack Obama announced on January 16, 2007, that he intended to run for president in 2008. He has submitted relevant documents to the US federal election agency on the same day and established a committee to evaluate the feasibility of his participation in the presidential election. Obama issued a statement on his website on the 16th, saying that he has been considering whether to participate in the 2008 presidential election for several months, but whether to participate will not depend on media publicity and personal ambitions. Over the past six years, decisions made by the federal government and problems ignored have put the United States in a very unsafe situation, and the United States has been plunged into an "unfortunate and costly" war that should never have been launched. While in Washington leaders are unable to cooperate in a practical way. Hillary announced her candidacy. On January 20, former President Clinton’s wife Hillary announced her candidacy for the 2008 US presidential election on her personal website. Her campaign slogan is: I'm here to win. The struggle between the two parties is fierce. Due to the large number of supporters of both parties within the party, a fierce vote-grabbing battle is indispensable, no less than the subsequent presidential election. Obama has focused on reaching young voters, especially online. In March 2007, Obama posted a question on "Yahoo! Answers" (the US version of Yahoo! Knowledge+) titled "How can we engage more people in the democratic process?" (How to attract people to participate in the democratic movement?), with more than 17,000 responses. Later, he also opened an account on the social networking site Facebook, and the page became very popular. Hillary's biggest advantage is that her husband Clinton and herself are women, which can easily attract the attention of female voters. When pollster Mark Melman asked 10 black women to choose their political hero, eight chose Hillary. Obama won the primary and Hillary withdrew. After a series of canvassing, on June 3, 2008 local time in the United States, the US Democratic presidential candidate Obama announced that he had won the party's primary and received the Democratic presidential nomination. On June 7, Hillary officially announced that she would stop running, calling on her voters to instead support Obama, the winner of the party's primary, to become president. 2. Nominate the vice president and accept the party’s nomination. On August 23, 2008, Obama announced that Joe Biden, the 65-year-old senior senator from Delaware, would become the Democratic Party’s vice presidential candidate. The Obama campaign website said: "Biden brings a lot of foreign policy experience, an admirable record of cross-party cooperation, and a direct business model." Analysts believe that Biden's diplomatic experience will help Obama govern, but he chooses the political arena Having a veteran as his running mate would undermine Obama's legitimacy in emphasizing change. On August 28, Obama accepted the Democratic presidential nomination at the Invesco Football Stadium in Denver, becoming the first black presidential candidate in the history of both parties in the United States. This day is also the forty-fifth anniversary of Martin Luther’s “I Have a Dream” speech in front of the Lincoln Memorial in Washington.

In his speech, Obama outlined his governing blueprint, covering the challenges of the 21st century such as economy, diplomacy, terrorism, poverty, climate change and disease. 3. Entering the presidential election After winning the party primary, Obama started his campaign. Especially for the Democratic Party's traditional state divisions and swing states (especially states with extremely large votes), such as Ohio, Indiana, Florida, Pennsylvania, etc. Achieved impressive results, with polls in multiple states showing that Obama overtook President Trump and party candidate McCain from a previous lag. Faced with Obama's initiative to attack traditional "red states" and being ahead of him in almost all subsequent opinion polls, McCain fought against the odds. As the presidential election approached, he gradually closed in on Obama, but the gap was still about 5% to 10%. 4. Winning the presidential election. At 11 pm Eastern Time on November 4, 2008, the vote count showed that Obama was elected as the 56th President of the United States with 349 votes, 163 votes ahead of McCain. He also became the first African-American president in U.S. history (Obama's father is a Kenyan citizen, and Obama's mother is a white American). Afterwards, Obama delivered a victory speech titled "Change in America" ??at his campaign headquarters in Chicago, saying that the time for change in the United States has arrived. He talked about the meaning of winning, McCain, family, the death of his grandmother, bipartisanship, and the power of America.
