There are two weeks to go before voting day for the US presidential election on November 3. Both parties’ candidates, Trump and Biden, fought online and offline. For the last two weeks, the advertising expenses of both sides totaled over US $100 million. < / P > < p > it is quite coincident and ironic that both former President Barack Obama, who came out of the camp to assist in the election, or the spokesperson of Trump’s campaign team, recently talked about the 2016 election. On the evening of October 21, local time, U.S. President trump moved to North Carolina to hold a campaign rally. His predecessor, Barack Obama, rushed to Philadelphia, Pennsylvania to deliver his first live speech to support Biden, his former deputy and this year’s presidential candidate. < / P > < p > “we can’t take it lightly. I don’t care about the poll results at all.” Obama said. He stressed that before the voting day of the 2016 general election, a series of poll results were not “counted” as the final results, “because many people stayed at home at that time, they were lazy and took it lightly. But not this time. This election can’t be like this again. < / P > < p > let’s look at the fundraising situation first – Trump’s huge capital advantage at the beginning of his re-election campaign has been reversed, and his fundraising performance lags behind Biden’s. By the end of September, Biden’s campaign had about $177 million in campaign funding, almost three times the $63 million held by Trump’s campaign. < / P > < p > let’s look at the spending – Biden team spent more in the sprint phase. The Biden team spent more than twice as much TV advertising as the trump team in September, according to data released by media tracking company advertising analysis. For the last two weeks of the campaign, Biden’s team has ordered $63.8 million in television ads in 20 states and trump has ordered $31.9 million. In addition, in Florida, an important swing state, billionaire Blumberg invested $100 million to support Biden, forcing trump to chase after him. With this big boost, the Biden team was able to use campaign money in other swing states. However, in view of the “money” disadvantage, Samantha ZAGAR, a spokesman for the trump campaign, refused to show weakness, citing the “precedent” that Hillary Clinton, the 2016 presidential candidate, was still defeated because of her strong financial strength, saying that “the trump campaign team has all the resources it needs in the final stage of the election”. < / P > < p > from fund-raising to election, from voting methods to hot topics, the new crown epidemic that ravages the United States can be said to reshape the U.S. general election in 2020. The U.S. government’s response to the epidemic is the most concerned and controversial topic. It is also one of the topics scheduled for the final debate between trump and Biden on October 22. Due to the epidemic situation, the proportion of early voting in this year’s general election has increased greatly. Recently, from Virginia to Wisconsin, voters wearing masks and long queues can be seen in front of many polling stations. People may have to wait at least an hour or two. < p > < p > < p > < p > according to the tracking statistics of “American election program”, more than 43 million American voters have already cast their ballots, which is equivalent to 31.3% of the total number of voters voting in the 2016 general election. In 2012, Republican presidential candidate Mitt Romney was also a member of the early voting force. He said on the 21st that he did not vote for trump, but declined to say whether he supported Biden. < / P > < p > after October full of “surprise”, the election still seems to be in the fog. “I’m afraid a political earthquake is needed to change the trajectory of the election,” said Ken speen, a Republican campaign adviser. However, campaign experts learned from the lessons of 2016 and stressed that Biden was in danger of losing the election because of the tight election situation in swing states.
