Sanders has had a heart attack. He came back swinging in the debate and looks fine. But come on — he’s had a heart attack at the age of 78. What happens if he has another one at any point before the election? Why should a party risk that? He’s also an actual socialist, and he hasn’t entertained — let alone engaged with — a new idea in decades. That’s appealing to millennial Marxists who have no memory of the 1970s, but Jeremy Corbyn was also a superstar with the youngsters a while back.

Warren is surging, but she is, I fear — yes, I’ll say it — unelectable. I may be wrong, but by pledging to rip everyone off their current private health insurance, it certainly seems like she has thrown away the core advantage of her side — health security. By floating the notion in the CNN forum that her future Secretary of Education would have to be approved by a transgender 9-year-old boy, she’s placing herself firmly inside a cultural revolution most Americans are deeply uncomfortable with.

And the Trump game plan against her writes itself: She’s a supercilious, smug, know-it-all Massachusetts liberal who reveals contempt for the deplorables the way Clinton did last time. The “first woman of color” to get hired as a professor at Harvard Law School is the stuff that GOP dreams are made on. That any suspicion of the viability of her candidacy will be ascribed entirely to misogyny will only help Trump, the way it did in 2016.
