I highly recommend this blog from AmThinker this morning: Biden's Great Leap Forward: A split second in Wisconsin. What the author documents is simply put:
From the beginning of the election Trump basically cruised along in WI with a 3-4 point lead. That margin held until, with 90% of the vote counted, at 3:42:20 AM the lead changed from a 3.6% Trump lead to a 0.3% Biden lead--courtesy of a sudden vote dump 17 times larger than other vote dumps, and which went 85% to Biden. A slim Biden lead having thus been established, the tabulation continued with a steady Biden lead.
The author concludes:
"The statistical word for this is bullfeathers."
The question: Why would a statistically impossible percentage of Biden votes be withheld from the count and appear so suddenly. The only plausible source for that number of votes would be Milwaukee, which would be close to the processing centers. The conclusion must be that those votes were deliberately withheld. Why? Or were they manufactured?
