It may be a crazy idea which just came to my mind, but keeping on the table that people will start the get very political next year (because the presidencial elections in the United States), having this domain to target poker players who also happen to be registered or have intentions to vote for the Democrat party. 
It would not be the first time I see a brand taking leverage on such important political event to increase their sales in the market. Though, it would be a gimmick which could be only pulled off once every 4 years or twice if we take in consideration the midterm elections. 

Anyways, OP.
Wish you luck with the selling of your domain, it has potential, but it would also require quite a big advertisement investment.
