President Joe Biden won 10 out of 15 states on Super Tuesday in 2020, ultimately securing his lead in the Democratic presidential primary race.

Ahead of Biden's night of wins, Vermont Sen. Bernie Sanders, an Independent, was a top contender in the Democratic presidential primary after tying for first place at the Iowa Caucus, and then winning both New Hampshire and Nevada.

However, Biden's slow start was given a boost when he was declared the victor of the South Carolina primary – the state where Democrats held their first contest this year. 

Just before Super Tuesday in 2020, Minnesota Sen. Amy Klobuchar, a Democrat, and Pete Buttigieg, a Democrat, ended their presidential bids and backed Biden ahead of the multi-state primary event, giving his campaign a final push to victory.

The night of Super Tuesday, Biden secured wins in Alabama, Arkansas, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, and Virginia. 

Sanders, Biden's last standing competition, dropped out of the race weeks later and endorsed the now-president.
