Lost amidst the firehose of lies uttered by Donald Trump at his address before Congress March 4, was a New Mexico Democratic congresswoman’s succinct description of the crisis facing the United States: Rep. Melanie Stansbury held a small sign that said, “This Is Not Normal” as Mr. Trump greeted lawmakers upon entering the chamber. That Texas Republican Rep. Lance Gooden ripped the sign from Ms. Stansbury’s hands was not surprising. What is remarkable was that more Democrats didn’t highlight Rep. Stansbury’s message.
