In 2016, Bernie Sanders started what he called a "revolution" as an independent candidate. He ran for president on a platform of progressive ideas in the United States such as free healthcare for all, but eventually lost the Democratic nomination to Hillary Clinton.

The 77-year-old is making a second attempt, launching his campaign to be Democratic candidate in 2020 and believes he still has what it takes to win the White House.

He has described Donald Trump as the most dangerous president in modern American history.

The list for the Democratic primary looks like it's a crowded one and one of the most diverse ever. At least 12 candidates so far have confirmed they'll run - dozens more have yet to decide.

There are already a record number of women, vast age differences between candidates and ethnic minorities.

But have any of them got what it takes to defeat Trump?
