The Arlington story has legs, and rightly so.
One thing that everyone on dKos can do to keep it in the (print) news and on the (broadcast) news is to use Google. search for something like {trump arlington}, click on every story — going as deep into the numbered list as you have time for.
Google suggests searches based on what searches have been made recently. Plenty of new companies follow up on stories which get lots of clicks. After all, the paper doesn’t record whether you read that story; the web page at least records that you looked at it.
I still push letter to the editor on this subject, but I know that there are people who would rather jump off a bridge than put words on paper.
