Voter Fraud? Nah, couldn't happen here.

 Bear in mind that we haven't been told why this guy was riding around with hundreds of ballots. I'm sure that there's a legitimate explanation. 

Hundreds of California recall ballots, drugs, loaded gun found in passed out felon’s car: police

I'm also sure that this was all "Machine errors," and no fraud involved in this district.

San Fernando Valley residents cast provisional ballots due to equipment issue

Here is something to think about. Suppose that those claiming that they were told at the polls that they already voted get to cast a provisional ballot. Suppose that ballot is actually counted, and some Left leaning millennial doesn't "Adjudicate" the ballot into the waste bin. You can say, Yay the system worked. The voter got to cast their provisional ballot, and their vote was counted.

But...

What about the voters that stayed home for this election, but still somehow had ballots cast in their name? Does anyone doubt that did not happen? Those that were informed of their ballots already being cast are no doubt the tip of the iceberg.
