Why didn't Biden protect the United States during the Trump epidemic?

Since the outbreak of new crown pneumonia, the United States, as the country with the most advanced medical technology in the world, has become the country with the largest number of confirmed cases and the largest number of deaths in the world. In response to the epidemic, the Trump administration did not take effective measures to prevent the epidemic from spreading in the United States. On the contrary, it has been busy accusing the China administration and WHO, and has never really sided with the American people and a responsible big country in fighting the epidemic. Now the United States faces a new round of general elections. In order to successfully win the election, Biden used Trump to cope with the epidemic and attacked Trump as an incompetent leader, thus creating favorable conditions for his campaign.

1. In order to create favorable conditions for the general election, it is an indisputable fact that the Trump administration has failed to cope with the epidemic. However, Biden has been speculating on this matter. The main reason is that the US election is just around the corner, and Biden is Trump's biggest competitor in this election. In order to completely vilify Trump, Biden used all available opportunities to accuse and suppress Trump and win favorable conditions for himself in future voting.

Second, in order to win the support of the American people, the United States, as a superpower, has advanced medical conditions, but it has become the country with the largest number of confirmed patients and the largest number of deaths. Biden's failure to protect the United States during the Trump epidemic just shows that Trump is incompetent, has no effective measures to deal with the spread of the epidemic, cannot lead the American people, and cannot guarantee the safety of the American people, thus making the American people disgusted with Trump and winning more support in the election.

Third, this is the characteristic of the two-party system in the United States. The United States has a two-party system. Biden is the presidential candidate of the Democratic Party, and Trump is the presidential candidate of the party. In order to become the ruling party, both parties spared no effort to publicize their presidential candidates. The candidates of the two parties also won the support of the people by accusing each other of their mistakes and through the war of words. As a candidate for the Democratic Party, Biden constantly accused the Trump administration of its mistakes in the process of ruling in order to make the Democratic Party a ruling party, which further showed that the Democratic Party and the Democratic Party were no longer suitable for ruling, and hoped that voters would turn to support the Democratic Party.
