Jonathan Chait dropping one hell of an argument:

Polarization has given any major party nominee a high enough floor of support that the term “unelectable” has no real place in the discussion. What’s more, every candidate in the race brings a suite of their own liabilities Trump could exploit. That said, the totality of the evidence suggests Sanders is an extremely, perhaps uniquely, risky nominee.

And

At this point there is hardly any serious evidence to believe that the best strategy to defeat Trump is to mobilize voters with a radical economic agenda. Public satisfaction with the economy is now at its highest point since the peak of the dot-com boom two decades ago. Trump has serious weaknesses of issues like health care, corruption, taxes, and the environment, and a majority of the public disapproves of Trump’s performance, but he does enjoy broad approval of his economic management. Therefore, his reelection strategy revolves around painting his opponents as radical and dangerous. You may not like me, he will argue, but my opponents are going to turn over the apple cart. A Sanders campaign seems almost designed to play directly into Trump’s message.

I don’t think Chait is wrong.
