Instinctively, Hillary Clinton has long seemed by far the more electable of the two Democratic candidates. She is, after all, an experienced, pragmatic moderate, whereas Sanders is a raving, arm-flapping elderly Jewish socialist from Vermont. Clinton is simply closer to the American mainstream, thus she is more attractive to a broader swath of voters. Sanders campaigners have grown used to hearing the heavy-hearted lament “I like Bernie, I just don’t think he can win.” And in typical previous American elections, this would be perfectly accurate.

But this is far from a typical previous American election. And recently, everything about the electability calculus has changed, due to one simple fact: Donald Trump is likely to be the Republican nominee for President. Given this reality, every Democratic strategic question must operate not on the basis of abstract electability against a hypothetical candidate, but specific electability against the actual Republican nominee, Donald Trump.

Here, a Clinton match-up is highly likely to be an unmitigated electoral disaster, whereas a Sanders candidacy stands a far better chance. Every one of Clinton’s (considerable) weaknesses plays to every one of Trump’s strengths, whereas every one of Trump’s (few) weaknesses plays to every one of Sanders’s strengths. From a purely pragmatic standpoint, running Clinton against Trump is a disastrous, suicidal proposition.

Her supporters insist that she has already been “tried and tested” against all the attacks that can be thrown at her. But this is not the case; she has never been subjected to the full brunt of attacks that come in a general presidential election. Bernie Sanders has ignored most tabloid dirt, treating it as a sensationalist distraction from real issues (“Enough with the damned emails!”) But for Donald Trump, sensationalist distractions are the whole game. He will attempt to crucify her. And it is very, very likely that he will succeed.

This campaigning style makes Hillary Clinton Donald Trump’s dream opponent. She gives him an endless amount to work with. The emails, Benghazi, Whitewater, Iraq, the Lewinsky scandal, Chinagate, Travelgate, the missing law firm records, Jeffrey Epstein, Kissinger, Marc Rich, Haiti, Clinton Foundation tax errors, Clinton Foundation conflicts of interest, “We were broke when we left the White House,” Goldman Sachs… There is enough material in Hillary Clinton’s background for Donald Trump to run with six times over.

Even a skilled campaigner would have a very difficult time parrying such endless attacks by Trump. Even the best campaigner would find it impossible to draw attention back to actual substantive policy issues, and would spend their every moment on the defensive. But Hillary Clinton is neither the best campaigner nor even a skilled one. In fact, she is a dreadful campaigner. She may be a skilled policymaker, but on the campaign trail she makes constant missteps and never realizes things have gone wrong until it’s too late.

Everyone knows this. Even among Democratic party operatives, she’s acknowledged as “awkward and uninspiring on the stump,” carrying “Bill’s baggage with none of Bill’s warmth.” New York magazine described her “failing to demonstrate the most elementary political skills, much less those learned at Toastmasters or Dale Carnegie.” Last year the White House was panicking at her levels of electoral incompetence, her questionable decisionmaking, and her inclination for taking sleazy shortcuts. More recently, noting Sanders’s catch-up in the polls, The Washington Post’s Jennifer Rubin said that she was a “rotten candidate” whose attacks on Sanders made no sense, and that “at some point, you cannot blame the national mood or a poor staff or a brilliant opponent for Hillary Clinton’s campaign woes.” Yet in a race against Trump, Hillary will be handicapped not only by her feeble campaigning skills, but the fact that she will have a sour national mood, a poor staff, and a brilliant opponent.

Every Democrat should take some time to fairly, dispassionately examine Clinton’s track record as a campaigner. Study how the ‘08 campaign was handled, and how this one has gone. Assess her strengths and weaknesses with as little bias or prejudice as possible. Then picture the race against Trump, and think about how it will unfold.

It’s easy to see that Trump has every single advantage. Because the Republican primary will be over, he can come at her from both right and left as he pleases. As the candidate who thundered against the Iraq War at the Republican debate, he can taunt Clinton over her support for it. He will paint her as a member of the corrupt political establishment, and will even offer proof: “Well, I know you can buy politicians, because I bought Senator Clinton. I gave her money, she came to my wedding.” He can make it appear that Hillary Clinton can be bought, that he can’t, and that he is in charge. It’s also hard to defend against, because it appears to be partly true. Any denial looks like a lie, thus making Hillary’s situation look even worse. And then, when she stumbles, he will mock her as incompetent.

Charges of misogyny against Trump won’t work. He is going to fill the press with the rape and harassment allegations against Bill Clinton and Hillary’s role in discrediting the victims (something that made even Lena Dunham deeply queasy.) He can always remind people that Hillary Clinton referred to Monica Lewinsky as a “narcissistic loony toon.” Furthermore, since Trump is not an anti-Planned Parenthood zealot (being the only one willing to stick up for women’s health in a room full of Republicans), it will be hard for Clinton to paint him as the usual anti-feminist right-winger.

Trump will capitalize on his reputation as a truth-teller, and be vicious about both Clinton’s sudden changes of position (e.g. the switch on gay marriage, plus the affected economic populism of her run against Sanders) and her perceived dishonesty. One can already imagine the monologue:
