A new Super PAC has reared its head and it’s made no secret of its first target: Rashida Tlaib. It comes as no surprise that Tlaib, the only Palestinian-American woman and the only Palestinian Democrat ever in Congress, is coming under severe attack ahead of her primary two months from now. But the nature of that attack is a particularly dangerous and pernicious one, and its nature is one that constitutes a unique and serious threat to not only advocates of Palestinian rights and freedom, but to progressives across the board.
