Yeah why not, they were already blaming the GOP for placing those flyers in Baltimore saying "MAKE SURE TO VOTE ON..." with the wrong date (which was without question done by Kathleen Kennedy-Townsend's operatives).
The Democrat Operatives do a variation of this in every election: The purposely put out a racist flyer, or misleading info, and blame the Republicans. They get away with it because their simple-minded Democrat constituency cannot think even to the first level of abstraction.
