I have yet to see the Trump campaign say anything about the abnormal spikes in turnout, the statistical improbabilities, the difference between the Congressional races and the top of the ticket, the failure to segregate ballots in PA, or any claims about specific batches of absentee ballots in MI or PA. Talking about "irregularities" and inability to observe is accurate but insufficient.
They need to be challenging the entire process in PA and MI, not just individual quirks. Trump needs to be setting the narrative stage for invalidating results wholesale out of Philadelphia, not just nitpicking some outrages already circulating on Twitter. Go from specific to general, not the other way around.
