"This Is, to Be Blunt, Political Suicide"

"You would think that parties of the center-left would grapple with this existential threat to their political viability. And some have. One reason Britain's Labour Party has done well in the last couple of years is that it has recognized the legitimacy of the issue. During the Brexit referendum, their leader, Jeremy Corbyn, expressed ambivalence toward remaining in the EU, careful not to lose his working-class base to the Europhobic right, recognizing the fears so many of his own supporters had about the impact of mass immigration on their lives, jobs, and culture. Even someone as leftist as Corbyn chose to be a pragmatist, trying to gain power, rather than a purist who might otherwise condemn his own voters as deplorable. And this is one reason why I have dwindling hopes that the Democratic Party will be able to defeat Trump in 2020."
