First look at a hot passage from a book out today by Josh Green of Bloomberg Businessweek, "Devil's Bargain: Steve Bannon, Donald Trump, and the Storming of the Presidency":

"[B]oth campaigns battled for a group of voters who would ultimately decide the race. ... Trump's data analysts gave them a nickname: 'double haters.' These were people who disliked both candidates but traditionally showed up at the polls to vote. They were a sizable bloc: 3 to 5 percent of the 15 million voters across seventeen battleground states that Trump's staff believed were persuadable.

"Early on, many indicated support for third‐party candidate Gary Johnson. But after a series of televised flubs, ... they largely abandoned him. ... Many refused to answer pollsters' questions ... These were the voters Clinton had hoped to shear off from Trump with her 'alt-right' speech in August. ... Comey's letter had the effect of convincing the double haters to finally choose."

How the "double haters" voted: The national exit poll found 18% of voters had an unfavorable opinion of both Trump and Clinton. Those voters went 47% for Trump, 30% for Clinton.
