My conclusion: It seems to me that the greatest danger that the DOJ lists is that jurors will be afraid to serve.

They quote Trump saying that D.C. “is over 95% anti-Trump."

So, specifically, people in that 95% may be afraid to serve. 

This is obviously a problem. 

I assume that extraordinary steps will be taken to protect the jurors. 

BTW, if you are new to reading court filings, the way to get the Cliff Notes version is to scroll through and read the headings.
