I believe that is because the states are in charge of doing it themselves. So some probably have done it. Maybe even most. Some certainly havent.

No state no matter the outcome of the election wants to publically say they screwed everything up. So it's not much of a surprise we havent heard much.

Somehow it was worth spending $40 million to investigate Trump for alleged election malfeasance with Russia. Totally justifiable. But to suggest we do the same to the DNC, China and the MSM? Inconceivable!
