Former city leaders John McKenna and Eugene C. Brune support incumbent mayor Joseph A. Curtatone in today’s primary.

Curtatone is facing challengers Suzanne L. Bremer and Richard J. Scirocco. A limousine with Scirocco posters in the windows and an SUV with a woman telling voters through an amplifier to "Vote for change, vote for Scirocco" was also seen on College Avenue today.

McKenna is a former alderman and Brune is the former mayor of the city and current register of deeds. They are both endorsing Curtatone. Brune predicted 5,700 voters would turn out to the polls today.

The city’s only other primary is in Ward 6 where Alderman Rebekah L. Gewirtz faces two challengers — Charles Chisholm and Robert Adams.
