The “Bostonians for Real Progress” super PAC, the newest outside group to enter the Boston mayor’s race, says it’s backing City Councillor At-Large Annissa Essaibi George for the top job.

“We believe Anissa is the best candidate, able to tackle all our challenges, while being a champion for Boston as a great place to work and live,” Carol Martinez, chair of the super PAC, said in a statement, pointing to Essaibi George's time as a city councillor as well as a “mother, teacher...and lifelong resident” of Boston.

The statement, which namechecked former mayors Marty Walsh and Thomas Menino, added: “She will build on the progress that was made under Mayor Walsh and Menino and bring it to the next level for this generation.”

The super PAC filed paperwork with Massachusetts campaign finance regulators on Wednesday.

Asked if the super PAC plans to canvass for the candidate or launch TV ads, as other super PACs have done for their respective candidates, a spokesperson for Bostonians for Real Progress said, "All options, including paid media, are on the table."

Two super PACs are already active in the mayor’s race: The hospitality workers union, UNITE HERE Local 26, has created a super PAC for Acting Mayor Kim Janey and has canvassing efforts already underway. The “Better Boston” super PAC is supporting District 4 Councillor Andrea Campbell and has taken to the Internet and television with ads touting Campbell’s biography.
