The AFL-CIO has reversed course and opened its endorsement process to two candidates for governor of Maryland who appeared ineligible for consideration a week ago.

As of last Thursday, Lt. Gov. Anthony G. Brown (D) was the only 2014 Democratic gubernatorial hopeful who met a new criterium for the highly sought-after endorsement: filing to run for office with the State Board of Elections.

Two of his rivals — Attorney General Douglas F. Gansler (D) and Del. Heather R. Mizeur (D-Montgomery) — made clear long ago that they’re in the race, but neither has been in a position to file paperwork with the state board. Under Maryland law, doing so requires a candidate to first name a running mate, which Gansler and Mizeur have not done.

On Wednesday, Fred D. Mason Jr., president of the Maryland State and District of Columbia AFL-CIO, said his organization would hear pitches from Gansler and Mizeur out of a desire to be “inclusive.”

“They will be interviewed and afforded the same opportunity as Anthony Brown,” Mason said, adding: “We certainly appreciate folks who took our process seriously.”

Mason said his group would make the same accommodation for Del. Jon S. Cardin (D-Baltimore County), a candidate for Attorney General who has yet to file his paperwork.

Three other candidates for the job have filed: Sen. Brian E. Frosh (D-Montgomery), Del. C. William Frick (D-Montgomery) and Del. Aisha N. Braveboy (D-Prince George’s).

The AFL-CIO plans to make its endorsements for statewide offices public in late October.
