The New York Times has this story about the Working Families Party’s victory in the May 5 special legislative election in Brooklyn. By contrast, when the Working Families Party scored a more impressive win for the Connecticut State Senate on February 24, 2015, the Times did not mention that. The Connecticut victory was more impressive because the Connecticut Working Families nominee defeated a Democratic Party nominee, whereas in New York the Democrats had no nominee on the ballot.
The BAN comment is of course correct.
One explanation may be that the New York Times is based in New York City where the WFP candidate just won the special election. Another may be space and other news items on any particular day. A third may be that the New York Times has been a Democratic Party mouthpiece since at least the Tilden/Hayes election.
