The U.S. National Congress, which has been delayed for more than a month because of the new outbreak, will be held in Milwaukee, Wisconsin from July 17 to 20. The Republican National Congress is scheduled to be held from 24 to 27, mainly in Charlotte, North Carolina. The Congress of the two parties is an important moment in the US general election campaign. The presidential and vice presidential candidates of the two parties will formally accept the nomination, and the general election will enter the final decisive stage. The new epidemic situation has reshaped the content, form and pattern of this year’s election campaign, and the Congress of the two parties has therefore taken on a new look. The National Congress of the two parties in the United States is held once every four years in the presidential election year, which is a key link in the election campaign of the two parties. The scale of the bipartisan meeting usually reaches tens of thousands of people, but this year it will be greatly reduced due to the new epidemic. < / P > < p > this year’s conference will be held remotely in an “unprecedented” online virtual form, and the highlight will be four consecutive nights of live TV and social media platform activities. According to the organizers, the live broadcast not only includes speeches by famous people such as former US presidents Barack Obama and Clinton, but also ordinary Americans. Former Vice President Biden is expected to receive the presidential nomination and deliver a speech in his hometown of Delaware on the evening of the 20th. Due to the twists and turns in the preparations for the Republican convention, all arrangements have not been officially announced so far. It has been determined that hundreds of party representatives will vote in Charlotte, the host city, on the opening day of the 24th to formally nominate current president trump as the Republican presidential candidate. Trump has previously revealed that he intends to give a speech on the White House lawn on the 27th to accept the nomination. As this will break the Convention, it has aroused doubts and criticism. According to US media reports, vice president burns will deliver a speech at the Fort McHenry National Monument near Baltimore, Maryland. Other speakers include trump family members such as first lady Melania, many well-known Republican politicians and some ordinary Americans who benefit from Trump’s government policies. The National Congress Committee said that “uniting the United States” is Biden’s key task. The message the Congress wants to convey is that “Biden is calm, compassionate and experienced. He is the leader that the United States needs now. He can unite Americans to get out of the crisis and chaos under trump.”. Compared with Hillary Clinton, the presidential candidate four years ago, Biden has less difficulty in achieving unity within the party, because he has locked in the presidential nomination very early, and he also takes into account the demands of the “progressives” in the party, and has won the support of Bernie Sanders, the former main opponent. In addition, it is widely expected that Biden will play the anti epidemic and economic cards in order to attract wider support, and respond to the current wave of reflection on racial relations in the United States, and his running mate, Kamala Harris, with multi-ethnic background, may give Biden more points. However, according to Fox News, a conservative media in the United States, the theme of the conference is “to commemorate the great American story”, highlighting the greatness, opportunity and bold leadership of President trump. In an interview with Xinhua, Christopher galdieri, an associate professor of political science at San Anselm college, said in an interview with Xinhua news agency that trump is expected to focus on issues such as law enforcement and immigration, and continue to shape his image of maintaining “law and order” to highlight party differences. The most important role of the Congress of the two parties is to build momentum for the election campaign. Due to the sharp reduction of on-site activities due to the epidemic situation this year, some people worry that the conference will lose a lot of attention, leading to the “discount” of canvassing effect. However, some experts believe that in the epidemic situation, the audience rating of the bipartisan conference will increase. Seth muskett, a political science professor at the University of Denver, said that with the growing political interest of Americans and the reduction of other activities under the epidemic situation, more people may choose to watch the bipartisan convention. Historically, the Party Congress has been able to boost the support rate of the party’s presidential candidates in the polls. According to the U.S. election analysis website “538”, since 1968, the Party Congress has brought an average of 5 percentage points to the support rate of presidential candidates. However, the website also points out that the “boost effect” of the Party Congress in recent presidential elections has weakened. Experts believe that this is related to the polarization of voters and the reduction of cross party voting willingness. In order to hedge the possible boost of the National Congress on Biden’s election, the trump campaign team has spared no effort to “spend a lot of money” on social media platforms to criticize Biden and Harris. Trump himself also plans to make targeted speeches in Minnesota, Wisconsin, Arizona and Pennsylvania during the Congress. It is worth noting how effective these measures can be.
