>>More: How Atlanta's mayor has emerged as one of Biden's top supporters

Long before Super Tuesday, Biden had already amassed far more endorsements than any other White House hopeful in Georgia, a collection of supporters that includes Atlanta Mayor Keisha Lance Bottoms, U.S. Rep. Sanford Bishop, former U.S. Sen. Max Cleland and dozens of influential state legislators.

But a surge of others rallied to him last week as he picked up support from party leaders worried the Vermont senator could bring lasting damage to down-ballot candidates.

Several prominent supporters of Mike Bloomberg flipped to Biden moments after the former New York mayor quit the race. So did former U.N. Ambassador Andrew Young, who announced his decision on Georgia Public Broadcasting's "Political Rewind."

And state Rep. Billy Mitchell, the president-elect of the National Black Caucus of State Legislators, promised that 90% of Georgia's Democratic lawmakers will soon announce their endorsements of Biden.

Sanders, who was trounced in Georgia in 2016, trails Biden badly in Georgia in polls. Still, both candidates are expected to visit Georgia ahead of the March 24 vote, the only Democratic contest that night. Biden has already scheduled a fundraiser in Buckhead two days before the primary.

Sanders has a smaller core of prominent supporters in the state, a group that includes former state Sen. Vincent Fort, former Clarkston Mayor and South Fulton councilman Khalid Kamau.
