Wait I'm OOTL, what did Campa-Najjar do? I thought he was just a boilerplate long-shot Justice Democrat.
Abandoned his principles on M4A and spouted Republican talking points against it. When his supporters pushed back, he compared them to Nazis (literally!) for pushing for M4A.
More recently, he decided to pander to a white supremacist group. He indicated that he would vote to confirm Amy Coney Barrett and gave support to investigating Hillary and even Obama. People got pissed and he apologized.
Recently a few people found that he's still a proud member of said white supremacist Facebook group and is still praising them.
The guy's not a Blue Dog or a Justice Democrat. Ammar Campa-Najjar is whatever is most convenient for Ammar Campa-Najjar at any given time.
