Unfortunately, that monster Doug Collins will probably win. Warnock will more than likely be his opponent, and has chance, but nothing like Abrams or Yaters would have had IMHO. Loeffler is toast, and will be lucky to avoid prison (hopefully she is prosecuted and convicted.)
Declined
Stacey Abrams, nominee for Governor of Georgia in 2018 and former minority leader of the Georgia House of Representatives (endorsed Raphael Warnock)
Sally Yates, former United States Deputy Attorney General <<<<< wish to hell she had run, as Abrams did not
Jason Carter, nominee for Governor of Georgia in 2014, former state senator, and grandson of former U.S. President Jimmy Carter (endorsed Raphael Warnock)
Keisha Lance Bottoms, mayor of Atlanta
Stacey Evans, candidate for Governor of Georgia in 2018 and former state representative (running for state house)
Kasim Reed, former mayor of Atlanta
Jen Jordan, state senator
Michelle Nunn, CEO of CARE USA and nominee for U.S. Senate in 2014
Sherry Boston, DeKalb County District Attorney
Mike Thurmond, DeKalb County chief executive, former Labor Commissioner of Georgia, and nominee for U.S. Senate in 2010
Nikema Williams, state senator and Chair of the Georgia Democratic Party
then you have the top 3 ones left, all of whom are running for the other Senate seat against the weaker David Perdue
Jon Ossoff, documentary filmmaker and nominee for Georgia's 6th congressional district in 2017 (running for Class 2 seat)
Teresa Tomlinson, former mayor of Columbus (running for Class 2 seat)
Sarah Riggs Amico, nominee for Lieutenant Governor of Georgia in 2018 (running for Class 2 seat)
hopefully one of them can beat that POS Perdue
and finally, you also one who declined but is running for re-election in the US House (smart move)
Lucy McBath, incumbent U.S. Representative for Georgia's 6th congressional district (running for re-election in the House)
In a perfect world, Abrams would have run against Perdue and Yates against Collins. Abrams is banking on being the VP (for which I 100% think she is the best pick) but I do not think Biden is going to go for her. I think she relishes a re-match against Kemp for Governor if she is not picked as the VP.
