Comparing the ratio of Biden-only to Straight Blue ballots across states may be the key to exposing ballot harvesting fraud. Most ballot harvesters paid for "Biden votes" will be too lazy to fill out complete ballots. I'd bet that, in most non-ballot harvesting states, almost all Biden votes appeared on straight blue ballots.
Also which states they are in — if the large gaps are only in swing states, that would be a huge indicator of fraud.
