Elizabeth Warren has left the race, and it's all our fault. Sniff! She was just too competent for us. Such was The Atlantic magazine epitaph for the Warren campaign written by Megan Garber on Thursday bemoaning what she thought was a public too unenlightened to appreciate the brilliance of the 1/1024th Native American candidate.  It was titled "America Punished Elizabeth Warren for Her Competence." Republicans had nothing to do with Warren's failure to thrive as a Democrat contender.
