When polls showed Biden in the lead, Trump had been hoping a "October surprise" would turn things around, but it never came.

Vaccine against Covid-19, a miraculous economic recovery, a blockbuster investigation by the Justice Department, a misstep by an adversary or a scandal involving Biden and Hunter's son are factors.

But in the end, October passed without any shocking surprises, leaving Trump still sinking in problems such as Covid-19 losing control, economic turmoil due to pandemic, controversy about style and behavior.

Several events have sparked upstream hopes for Trump's team such as empty judges at the Supreme Court, street protests that the President seeks to blame on Democrats and

But in the end, no matter the weight enough to help Trump turn the tables.

As election day approaches, new cases of nCoV in the US skyrocketed again, rising by nearly 100,000 on October 30, especially in the Midwest, home to a number of key battlefield states.

"The October surprise happened in March," said Republican strategist Mike DuHaime, referring to the time of the Covid-19 outbreak in the US.

Jennifer Palmieri, Hillary Clinton's top adviser in 2016, said that given the current US context, the idea that the position is reversed by just one event is highly unlikely.

Trump still has a chance to win.

However, Trump's 2016 victory was based not only on his appeal to this group of voters but also on events that rocked the final weeks of the track, in which the FBI opened an investigation with calves.

But Biden is not Clinton.

In contrast, the Trump campaign "survived" another seemingly "October surprise", when the media at the time made public videos of him making vulgar comments about women.

In US election history, there have been many times in September or October that upset a candidate's campaign.

But usually, "October surprises" are "endogenous" events - negative news about a rival is released by one side at a time when voters are most interested.

Some politicians wonder whether in this era, the "October surprise" really existed.

The two biggest "exogenous" issues in the race are the death of Supreme Court judge Ruth Bader Ginsburg and the President hospitalized for Covid-19 in early October. Despite Democrats,

Trump's infection with nCoV does not make Americans sympathize with him, but it further shows that he has ignored medical recommendations.

"It's easy to see how this election could be different if Trump takes different actions and policies," said David Wasserman, editor of the Cook Poli Report.

Mrs. Clinton has argued that Comey's letter to Congress announcing the reopening of the email investigation was the main factor in her defeat.

For months, Democrats have been worried about what Trump could do in the face of a tough war.

But most of what Trump is trying to do to rock the race doesn't seem to be working.

That doesn't mean Trump isn't trying to use government levers to rock the race.

He complained that Secretary of State Mike Pompeo did not release an email from Clinton that he said "would reveal the actions of the Democrats to sabotage his 2016 campaign".

When Trump campaigned across the US, he complained at most of the rallies that the media had not paid enough attention to the charges against Hunter Biden.

His press secretary, Kayleigh McEnany, visited the area behind Air Force One one recent night to ask reporters to accompany Trump on campaigning to watch Tucker Carlson interview Tony Bobulinski

But even some Republicans say the news has not made headlines.

Still, some fear there could be a November surprise. Democrats worry that Trump and the Republicans could upset the election through voter compression tactics and litigation over

However, DuHaime said the situation in 2020 is very different from 2016. And Biden is not a long-standing target of attack by conservatives like Clinton.
