Joe Biden (Joe Biden) on Sunday (July 21) announced the withdrawal from the presidential election, which surprised American voters.

Since his performance with Trump's live broadcast debate last month, 81 -year -old Bayeng has faced more and more pressure on him to refund the election.

Bayeng said when he announced his withdrawal from the presidential campaign "the best interest in the Democratic Party and the country."But he will continue to stay in office and complete the last six months of his term.

Bynden refund: What are the situations at present?

Although Biden will perform the remaining president's term, he has supported Vice President Kamala Harris (Chinese name He Jinli) to succeed him as the Democratic Party nominated.

Harris received his support about half an hour after Biden announced that he had been retired about half an hour, and Harris had begun sending a campaign to raise money email.

Harris said she intends to "win" nominations and "do everything I can ... unite our country and defeat Trump (Trump)."

"Actblue", which provides public donations to Democratic candidates, said that donations have increased since Biden announced his refund.Since Harris launched a campaign, grassroots supporters have raised $ 46.7 million.

Many senior Democrats also expressed their support to support Harris, including Gavin Newsom, Governor of California, who are considered to be a Bedden substitute.Pete Buttigieg.

According to US media reports, a source who learned about Harris programs said that Gretchen Whitmer, governor of Michigan, would not challenge Harris' nomination.

Bynden's refund means that Republican nominated and Trump, 78, became the oldest nomination in the history of presidential campaign.Trump called on the next presidential nomination in September to broadcast on Fox instead of the Broadcasting Corporation (ABC).

Some of the most enthusiastic supporters of Trump, including Marjorie Taylor Greene and Greg Abbott, all said that Trump can be elected in November in NovemberIt is easy to defeat Harris.

A spokesman for the first lady Jill Biden told BBC that her husband would support him, no matter what he chose ", and said that Gil was still the" biggest believers "in Biden.

What will happen now?

Only one month before the Democratic National Congress, this decision pushed the Democratic Party into the unknown area.

Last withdrawal from the re -election was the then President of the 1968 election, Lyndon Baines Johnson. The path of nomination of new candidates on the election day is not clear.

After sweeping almost all primary elections and party group meetings across the country, Biden has won the support commitment of 3,896 Democratic representatives.

Although Biden's support has made Harris a most likely nomination candidate, after Biden announced his refund, they no longer insist on their previous commitments.

But in the end, they will vote for the person they choose.

Is there a public conference?

The National Congress of the Democratic Party will be held on August 19.

If the Democratic Party does not unite to support new candidates, this may laid the foundation for the first public conference since 1968.

This means that if many candidates appear, the representatives can freely decide who to vote for.

Candidates need to sign at least 300 representatives (no more than 50 representatives from a state), their names will appear on the votes.

The first round of voting will be carried out among 3,900 promised representatives, including voters who are considered loyal to the Democratic Party.

If there is no candidate to get a majority ticket after the first round, more rounds of voting will be performed.These rounds of voting will include super representatives -political party leaders and elected officials -they will vote until they choose nominations.

In order to get the nomination of the party, the candidate needs 1976 representative votes.

Who may challenge Harris?

In recent weeks, as required to refund the election, some potential substitutes have appeared.

Gretchen Whitmer, Government Governor of the Democratic Party of Michigan, was nominated as a candidate, but she said that if Bayeng stepped down, she would not consider the election.

When Bayeng announced his refund for a few minutes on Sunday, she said that she would do everything possible to "elected Democrats and stop Trump."

Other choices include Gavin Newsom (Gavin Newsom, Gavin Newson), Minister of Communications Pete Buttigieg, and Pennsylvana Governor Joshua Charlo (Josh Shapiro, Josha Sherlo).

If Harris eventually won nominations, some of them may be considered to compete with President.
