After the announcement of Kamala Harris as running mate, her and Biden’s combination was a hit. Recently, some people have come to a “strong material”, saying that former President Obama has repeatedly criticized Biden in private. Behind the “friendship” between the two is actually a more complex relationship. Although Obama has made it clear that he supports Biden’s campaign, a person who has talked to Obama said that Obama had questioned Biden’s ability and criticized Biden for not knowing the voters, according to the US “politician” news network on August 16, local time. The man told “politician” news that Obama had made some pungent criticisms. He said Obama had previously privately warned, “don’t underestimate Biden’s ability to screw things up.” Long before the primary, Obama mercilessly criticized Biden for not knowing the voters. “Politicians” have previously reported how Obama built a close relationship with Iowa voters when he was talking to a candidate in November for the year. Then Obama turned to Biden: “do you know which of the candidates is not close to the voters? It’s Joe Biden. ” “Politician” news network also pointed out that the relationship between Obama and Biden team was rather tense in the primary election in early 2020. At that time, Obama refused to voice his support for any candidate, and many members of the original Obama campaign either stayed out of the game or were working for candidates other than Biden. An aide to Biden’s team believes that Obama has given too little help to Biden. Biden complained to his team this year that Obama did not help him win over black voters in the South Carolina primaries, and “didn’t even move a finger.”. According to a number of white house people, Obama was more inclined to let Hillary Clinton become the next candidate after his re-election in 2012, according to the report. In 2013, people can already see Obama’s constant praise of Hillary Clinton in interviews, while Biden’s team was preparing for the 2016 election. < / P > < p > it is also recalled that from mid-2013 to 2015, several aides and senior advisers of the Obama team joined Hillary Clinton’s team. Several of Clinton’s former campaign aides said the actions were so obvious that they doubted for a time whether Obama mistook Biden as too old to be interested in the campaign. Biden also recalled that most of Obama’s staff were helping Hillary. In 2015, when asked by a reporter whether he preferred Hillary Clinton or Biden, Obama refused to answer this question. His spokesman simply told reporters, “President Obama clearly respects Biden’s wisdom, experience, compassion and integrity.”. Some officials of the former Obama administration argued that Obama’s “partiality” to Hillary Clinton was more a “recognition” of her ability. Not only Obama, but also Hillary Clinton has been worried about Biden’s future. In October last year, Hillary Clinton also considered whether to re-enter the election campaign or even made some special preparations, but she finally gave up the idea. < p > < p > in April this year, Bernie Sanders announced that he would withdraw from the election and support Biden, and then Obama released a video to officially support Biden. Obama praised Biden, saying: “I believe Biden has all the qualities we need from the president now I know he will bring more outstanding people to his side. ” Since then, Obama and Biden have also held fund-raising activities, together with a video conversation for publicity. However, some of Biden’s allies believe that Obama’s stance this year is far from straightforward compared with his speech in support of Hillary Clinton in 2016. “I don’t think anyone is better suited to be president than her,” Obama said four years ago However, regarding Obama’s support, Anita Dunn, a consultant to Biden, also said that Biden had already understood that he had to rely on himself to win support, and that people could not vote for Obama with the mentality of “this is Obama’s third term”. Biden, who has been “underrated” for a long time, now dominates the polls. Biden is 9 percent ahead of trump in the latest poll released by the Wall Street Journal and NBC on the 16th. Biden also had 49% of the 11 key “battleground states” that dominated the outcome, seven points ahead of trump. However, pollster Peter Hart points out that although Biden is currently ahead in the polls, there is still a lot of uncertainty about the election because many voters say they don’t know whether Biden can be qualified for the presidency.
