This issue (not the OP article, which is a trainwreck) seems like a couple people read too much into it, and told their story to other political operatives (not surprising given those involved) who used it to make a set of hit pieces and protect a vulnerable incumbent in a primary.
I maintain this (and other hit pieces aimed at up and coming dems) are mere political stunts by Republicans and right-wing Democrats looking to bloody the progressives ahead of November.
