Joe Biden has won the Maine Democratic primary, according to AP.

Why it matters: It's the last Super Tuesday primary to be called and further adds to Biden's delegate lead.

The big picture: Aggregated polling averages leading up to Super Tuesday showed Bernie Sanders with a strong lead in Maine, where 24 delegates are up for grabs. But Biden saw a huge day-of voting surge after Pete Buttigieg and Amy Klobuchar suspended their campaigns and endorsed the former vice president hours before polls opened.

Joe Biden is projected to win the Arkansas Democratic primary with 31 delegates at stake, according to the AP.

The big picture: It's Biden's 6th victory of the night in a southern state, with only Texas remaining. Biden received a boost the day before voting opened on Tuesday after Sen. Amy Klobuchar and Pete Buttigieg relinquished their White House bids and endorsed the former vice president. Former Rep. Beto O'Rourke, who had dropped out of the race in November, also endorsed Biden Monday night.
