Sen. Bernie Sanders Announces his Candidacy for President on Vermont Public Radio

The 77-year-old self-described democratic socialist unsuccessfully challenged Hillary Clinton in the Democratic presidential primary in 2016, and was widely credited for reshaping the party's politics and moving it to the left.

Sanders, who was the runner-up for the Democratic presidential nomination in the 2016 election, is poised to run a campaign that focuses largely on grassroots work from his supporters.

The early eye-popping sum raised by the senator from Vermont puts him on track to leapfrog the $1.5 million his campaign raised in the first 24 hours after announcing his White House run in 2015. What Warren has going for her is that Democrats have either nominated a minority or a woman in the last two primaries.

In an interview with CNN after the initial allegations surfaced, Mr Sanders apologised but also noted he was "a little busy running around the country trying to make the case".

Mr Sanders upended the party establishment by siphoning support from Democrats' liberal wing and young people, touching off a leftist movement that ushered progressives like freshman Representative Alexandria Ocasio-Cortez into office in the November midterm elections.

The crowded field includes a number of other candidates who will likely make strong appeals to the Democratic base including Harris and Sens.

Sanders garnered passionate support among young liberals with his calls for universal health care, a $15 minimum wage and free public university education.

Sanders has spent much of the past few years spreading his message and developing relationships with like-minded officials and activists during exhaustive travels around the country - with a particular eye on states won by Trump in 2016 - and via his unrivaled digital operation.

Sanders, who lost against Secretary of State Hillary Clinton in the 2016 primary, faces competition for the Democratic nomination from fellow Sens. They are extreme. The American people just won't accept those ideas.' Well, you know what's happened in over three years?

It was not immediately known how big the average donation was, the aide said, although Sanders said in a tweet that supporters from all 50 states have already donated.

"If you look at polling in this country", said Sanders, "what you find is that a whole lot of people are dissatisfied with both the Democratic and Republican parties, and more and more people are seeing themselves as independents".

"What they experienced was absolutely unacceptable and certainly not what a progressive campaign or any campaign should be about", Sanders said at a news conference in January.

Sanders had won 86.1 percent of the vote in Vermont, and his supporters believed that Vermont's superdelegates should have cast their vote for him in the Democratic National Convention because of it.

Sanders used his announcement to attack President Donald Trump, saying: 'We are living in a pivotal and unsafe moment in American history.

Sanders had been dogged by controversy after women working on his 2016 campaign alleged they were harassed by male staffers, putting the politician in an awkward position in the #MeToo era.
