I don't see this as a partisan issue. The same motivations exist for anyone in their position to commit fraud. I doubt people of one political tribe are any more immune to them than the those of another. Perhaps it is more likely for fraud to occur from a minority party given they are less likely to succeed without it.

>The Brennan Center summarized almost 200 errors in election machines from 2002 to 2008, many of which happened repeatedly in different jurisdictions, which had no clearinghouse to learn from each other.

The analysis done from Brennan gives me opposite of hope if you read everything published by them.
