Washington (CNN) Stacey Abrams, the 44-year-old progressive vying to become the nation's first black female governor in Georgia, has become a magnet for Democrats considering presidential bids in 2020.

Four Democrats who endorsed Abrams for governor are already planning Georgia trips this fall and using their email lists to raise money for Abrams.

New York Sen. Kirsten Gillibrand will travel to Georgia in October to campaign with Abrams, a Gillibrand aide said, and will raise money for her through Gillibrand's email list.

California Sen. Kamala Harris sent a fundraising email for Abrams on Wednesday and campaigned with her before the primary. Now, a Harris aide said, she is planning a trip to Georgia ahead of November's election.
