Sigh. Voter fraud happens. It has been investigated over and over and over again with so few instances actually found that it is laughable.
In fact, out of 1 billion ballots cast, they found 31 credible incidents.

Let that sink in. In every case of the initially reported "massive fraud" cases, we end up with the vast majority falling into the category of simple discrepancies (e.g. missing middle initials, missing apartment numbers, or simple clerical errors in spelling), duplicate registrations because people moved from one state (or district) to another, people who died since the last election, etc.
In fact, that is another thing you need to let sink in. Over 7,000 people die in the US every single day. So if you were to look a week after the Nov 8 election, you are absolutely going to find tens of thousands of people who are dead yet voted...just because they died since they voted.
If you are really curious about election fraud, you need to go a lot deeper than the mass media (that you distrust about every other issue BTW). Look at the actual fraud investigation reports. The Washington Post article references one of the few very serious studies into the matter and is heavily documented with references (223 of them) so you can validate the veracity and accuracy of that study -
