Hillary Clinton needs someone to tell her what a bad idea looks like.

One of the former Democratic presidential candidate’s most renowned weaknesses has always been her tendency to reward loyalty over competence, with the effect of saddling her with ineffectual staffers like the disastrous Mark Penn or the data-worshipping Robby Mook. And as Shattered, the behind-the-scenes tell-all about Clinton’s 2016 campaign, argued, her campaign staff was too afraid of missing out on cushy White House jobs to criticize her.

All of which brings us to the present moment, where Clinton has made the baffling decision to not just attack Bernie Sanders in her new book, but to double down on her attacks in subsequent interviews.
