Chalk up more labor support for Chris Koster’s attorney general campaign.

The converted Democrat today announced the support of the Carpenter’s District Council, which represents two dozen locals around the St. Louis area.

“Chris has demonstrated vast knowledge of the issues that matter most to our members,” said Terry Nelson, the council’s executive secretary-treasurer.

Labor has been split in the Democratic fight for the attorney general nomination, perhaps the most competitive August contest for the Dems. (With apologies to the race for state treasurer.)

The Carpenters join the Teamsters and State Firefighters’ Council in backing Koster. The SEIU is standing behind Margaret Donnelly, while AFSCME is in Jeff Harris’ corner.
