Is it Bernie or bust?

Voters across America are preparing to take part in the biggest day of the 2020 election so far. More than a year after the first Democratic candidates joined the race to take on Donald Trump, we've now reached Super Tuesday. Fourteen states will vote on which Democrat they want to run in November's election. Bernie Sanders is in the lead after the early contests. By Wednesday, we could have a clearer picture of who the nominee will be. (Image: Bernie Sanders. Credit: EPA)
