Former US Vice President Biden, who has locked in the US presidential nomination, nominated US Senator Kamala Harris as the vice presidential candidate on the 11th. This is the first time in American history that a woman of black and Asian descent has been nominated as a vice presidential candidate by a major political party in the United States. < / P > < p > as early as in March this year, Biden said that if he was nominated as a presidential candidate, he would choose a female vice presidential candidate as his partner. Because of the large number of candidates and fierce competition, speculation about who Biden will eventually choose has been endless. With the opening of the 2020 National Congress, the US media is paying more and more attention to Biden’s decision. At 4:17 p.m. EDT on the 11th, Biden put an end to the suspense. He announced on social media that he chose Harris as his running mate, praising her as “a fighter for the little” and “one of the best public servants” in the United States. Harris responded on social media that Biden is honored to join his team as a vice presidential candidate to unite the American people. It’s not easy for Harris to get out of the siege. Several of her main rivals are very competitive, including Susan Rice, assistant to national security affairs under the Obama administration, Elizabeth Warren, a former U.S. senator from Massachusetts, and Gov. Gretchen Whitmer, the governor of Michigan, who has received much attention for her anti epidemic work. < / P > < p > Biden’s decision was supported by people from all walks of life. Biden’s old partner, former President Barack Obama, praised Biden’s choice and recognized Harris’s ability and personality. Inside the progressive camp, Vermont Senator Bernie Sanders also expressed strong support for Biden and Harris. In October 1964, Harris was born into an immigrant family in Oakland, California. Her father is an emeritus professor of economics at Stanford University in the United States from Jamaica, and her mother is a cancer researcher from India. Harris graduated from Howard University, where he received a dual degree in political science and economics, and later entered Hastings Law School of the University of California to study law. < / P > < p > Harris worked as a district attorney in San Francisco for a long time. He was elected Attorney General of California in 2010. During his tenure, he vigorously promoted judicial reform and called himself “progressive prosecutor”. In 2016, Harris was elected to the U.S. Senate of California. On Capitol Hill, Harris, a newcomer, had no “green feeling” and soon established his reputation by “iron teeth and copper teeth”. In the Senate hearings, videos of her questioning people have repeatedly attracted attention on social media. < / P > < p > in January 2019, Harris announced that he would participate in the presidential primaries. For a long time, she was regarded by all parties as one of the most powerful presidential candidates, but her high exposure failed to be transformed into the “fuel” for election. She finally announced her withdrawal at the end of 2019 due to lack of funds. < / P > < p > it is worth mentioning that in a primary debate in the summer of 2019, Harris once questioned Biden’s legislative record on race issues when he was a U.S. senator. Biden responded harshly and was full of gunpowder, which made headlines at that time. Harris was also crowned as “ambitious”. However, the two soon “cleared the ice.”. In March this year, Harris announced his support for Biden’s presidential campaign and began to actively support him. < / P > < p > Biden has many considerations in choosing Harris. First of all, Harris has no obvious weakness, and his campaign ideas are not significantly different from Biden’s. As one of the important candidates in the pre election stage, she not only has campaign experience, but also has been severely censored by competitors and the media, so she is less likely to be exposed in the election. Former Wisconsin governor Scott Walker said the running mate is to supplement the candidates, but the most important thing is “not to mess up.”. < / P > < p > secondly, among the important topics of this year’s general election, the issue of race has received special attention, which is a bonus item of Harris with multi-ethnic and legal professional background. In late May, Freud, an African American man, died after being violently executed by the police. The incident not only triggered large-scale demonstrations across the United States, but also triggered a comprehensive reflection on racial issues. Darrell West, a senior researcher at the Brookings Institution of the United States, said that Harris is respected by black people, women, immigrants and other important groups and can bring real help to Biden’s campaign. At the same time, Harris has long served in the judicial system and has rich legal experience. In the wave of protest triggered by Freud’s death, Harris’s position on civil rights and criminal justice system reform was highly praised by many voters. Third, Biden will turn 78 on November 20, and if he wins the election, he will become the oldest president of the United States when he comes to power. Harris is only 55 years old now. She can not only inject more vitality into Biden’s campaign, but also enhance Biden’s campaign image and hedge opponents’ doubts about the stability of his administration. < / P > < p > in addition, Harris is sharp in speech, good at debating, familiar with the content and rhythm of the presidential campaign, and knows how to deal with queries and criticisms from the media and opponents. As a vice presidential candidate, Harris will soon face a major task is to face the current U.S. Vice President burns at the vice president’s televised debate in Salt Lake City, Utah, in early October.
