The Connecticut Working Families Party almost always nominates candidates who are also Democratic nominees. However, in the upcoming April 25 special election to fill the vacant state house seat in the 7th district in Hartford, the Working Families Party is running someone in opposition to the Democratic nominee.
The Working Families nominee is Joshua M. Hall. The Democratic nominee is Rickey Pinckney. They are the only candidates running. See this story. In the November 2016 election, the only person on the ballot for this seat was Doug McCrory, who was the Democratic nominee but not the nominee of any other party. The Working Families Party did not involve itself in the 7th district in the November 2016 election. The seat is empty because Representative McCrory resigned earlier this year, because he had been elected to the State Senate in a special election in February 2017.
