Let's break this dumb list down...
Ok, so there are three examples here. They aren't clear which party the dead people voted for.
Ok, this has more potential. Although it sounds like whoever was behind this fraud messed up by not letting the fraudulent voters know what there job was. How many of them successfully lobbied a democratic vote?
700 people cast two ballots! That's terrible. Who did they vote for? Who organized this?
I'm going to stop there, but Pennsylvania actually come up two more times, so it is clear that they've got issues. But are they rigging it for one side? I mean, sure, you could assume allowing illegals to vote is clearly an attempt to get more Democrat votes. Except no one seems to have let those illegals know what their role is in this. It is also pretty clear that the registration is tied to driver's licenses, which is more of an example of dumb bureaucratic paperwork practices than actual fraud.
So basically all of these examples don't clearly favor one party, they seem highly disorganized, and in a nation of 300 million, they are still a drop in the bucket. I'm going to go with stupidity over fraud.
