Yes, no kidding, people who pass away are not automatically expunged from the voter rolls, Social Security, driver's licenses, and a whole host of other things.
That does not establish a wide pattern of voter fraud numbering in the milions, nor that any such voter fraud is exclusive to a certain party.
Most registered living voters, in fact, do not even vote PERIOD, so getting grandma's zombie to vote is not going to make much of a dent.
Also, aren't those 'fake news' sources?
