Joe Biden hinted about intentions to enter the presidential race.

Vice President Joe Biden, in his speech on Labor Day at a rally in downtown Pittsburgh, called for action to reduce economic inequality, and demonstrated the approach he intends to take during the election campaign.

Despite his 72 of the year, Biden looked energetic and emotional. He took a walk along the main street of Pittsburgh, greeting people who met him with exclamations: “Participate, Joe, participate!”.

So far, Biden has not given a definite answer to the question about his participation in the struggle for the nomination from the Democratic Party. Currently, the two leading campaigners are Hillary Clinton - a favorite of the Democratic race - and Bernie Sanders, who is positioning himself as a socialist.

Last week, Biden said that he was not sure that he had enough mental strength for the political struggle after his son Bo died from cancer in May. According to various versions, Joe Biden took the time from the end of September to November to answer Bo's call to run for president.

Richard Tramka, president of the AFL-CIO trade union, who accompanied Biden along the parade, said he didn’t know whether Biden would take part in the race, but added: “If you are looking for energy, then this is a great place to get energy today.” ".

A fresh poll from NBC News / Marist over the weekend was sensational for Biden’s supporters, showing that despite the fact that today the vice president is not a candidate, his popularity is growing in Iowa and New Hampshire - the states where the primaries run first .

Presenting Biden before his speech, Tram and Leo Gerard, the leader of the United Steelworkers union, did not stint on the praise of the vice-president, born in Scranton, Pennsylvania. "He never let us down," said Gerard.

In his speech, Biden linked the fact that the most affluent Americans get too much of their social wealth with the existing tax system.

Previously reportedthat interest in the nomination of Biden has increased markedly against the backdrop of the fact that Hillary Clinton is becoming increasingly difficult to secure widespread popularity among Democrats.

Issues related to the fact that she used her personal email account as secretary of state continue to cloud Clinton’s election campaign.

Democrats hope that Biden will make a decision before the first democratic televised debates, which will be held next month.
