It's like Rush Limbaugh blaming 4 million phantom conservatives for not showing up to elect Romney, who bested McCain by a million votes, when the Democrats can point to 4.6 to 8.2 million actual Obama voters who abandoned Hillary.
When it comes to the establishment in the two political parties not getting it, the Democrats do it better as usual.
From "Seething liberals vow revolution in Democratic Party" at The Hill:
In an election determined by enthusiasm, some blame Bernie Sanders supporters for either not showing up or for suppressing turnout by refusing to rally behind Clinton at an earlier date.
“The Sanders people should be mad at themselves,” said one well-connected Democratic strategist. “If they had come out to vote, Donald Trump wouldn’t be president. If they were trying to prove a point, all they’ve done is further damage everything they claim to be fighting for. It’s somewhat typical of that crowd.” ...
“Progressives showed up,” [Jacob] Limon said, noting that the election in Texas was closer than it has been in 20 years. The problem, he said, was Clinton’s trustworthiness.
