Republicans have issues, but Democrats have them too. Witness the two individuals who dominated this week’s news—and who conveniently represent the left’s most crippling problems.

Hillary Clinton is again everywhere, touting her new memoir and adding to the list of who and what are to blame for her loss: Joe Biden, Bernie Sanders, Barack Obama, James Comey, Jill Stein, Vladimir Putin, Julian Assange, Anthony Weiner, sexism, misogyny, the New York Times, lazy women, liberal activists and the “godforsaken Electoral College.” All she’s missing is climate change.

Hillary’s take on “What Happened” has unsurprisingly unleashed another round of analysis about her mistakes—Wisconsin, deplorables, email. These sorts of detailed postmortems of failed campaigns are popular, but they tend to obscure the bigger reasons for failure. In this case: The Democratic Party saddled itself with an ethically compromised and joyless candidate, because it had nobody else.

Hillary spent eight years planning her first presidential bid, and the next eight warning Democrats not to get in the way of her second. The Clinton Foundation was erected to serve as bank and Rolodex, and to enable the Clintons to retain their grip over the party. And that party was committed to a Clinton coronation, right up to Mr. Sanders’s cheeky assault.

Mr. Obama aided Mrs. Clinton’s ambitions by decimating his party. By the time Barack Obama finished his eight years in office, his party held 65 fewer House seats, 14 fewer governorships and controlled 30 fewer state legislatures. It had turned a once-filibuster-proof Senate majority into minority status. The big-tent Democratic coalition shriveled to a coastal, progressive minority, wiping out a generation of Democratic politicians and most of the party’s political diversity.


And so the party nominated perhaps the only Democrat in the country who could rival Donald Trump in unpopularity—and beat him in untrustworthiness. Mr. Sanders refused to go after Mrs. Clinton on her ethical baggage, even though it was her biggest weakness and despite how glaringly obvious was the risk that her foundation and server scandals would hobble a general-election campaign. The parties gave the country a choice between two unpopular people, and the country disliked her more. The real question is how Democrats rebuild a party whose senior leaders in the House boast an average age of 72 and which has almost no young, experienced up-and-comers.

Which brings us to Mr. Sanders, the symbol of Democrats’ other big problem. This week the senator, flanked by about one-third of Senate Democrats, released his “Medicare for All” proposal to nationalize health care. These are the ascendant voices in the party. Yet there are few of them, because their agenda is highly unpopular.

Mr. Sanders was an unexpected force in the primary, though mostly because he wasn’t Hillary. Sanders supporters resent this argument, and claim the only reason his agenda didn’t triumph is because the DNC robbed him of the election. If so, why did Bernie’s people and ideas fail spectacularly everywhere else on the ballot?

In Wisconsin Mr. Sanders campaigned for Russ Feingold, who promised a $15 federal minimum wage, an end to trade deals and free college. Mr. Feingold lost to Republican Sen. Ron Johnson. In upstate New York, in a white, working-class district, Mr. Sanders endorsed Zephyr Teachout, who railed against bankers and lobbyists, fought fracking and Citizens United, and opposed trade. Republican John Faso beat her for the open seat by eight percentage points, on a promise to kill Dodd-Frank. Democrats wouldn’t even vote for Tim Canova, the man who primaried Mr. Sanders’s archenemy, Debbie Wasserman Schultz.


An extraordinary 79% of Colorado voters said no to a ballot initiative for ColoradoCare, the state version of Mr. Sanders’s universal health-care proposal. This in a state that Hillary Clinton won. Liberal Vermont pulled its own single-payer plug in 2014. In California, Mr. Sanders endorsed and campaigned for Proposition 61, which was designed to impose prescription drug price controls. It went down to substantial defeat in a state Mrs. Clinton won by 30 points.

Progressives will argue that all they need to elect a Bernie or an Elizabeth is the right way of pitching their “populist” policies of free health care or price-controlled drugs to the white working class and independents. But so far they’ve been unable to sell them even to bright blue states. And this wishful thinking ignores that even if voters supported some of those provisions, they’d also have to swallow a progressive agenda that includes an energy crackdown, a retreat from the terror fight, and the culture of identity politics.

Republicans have failed to unite or govern or pass their biggest priorities. But the political analysts are setting themselves up for another surprise if they ignore the big reasons Democrats lost this election, and what comes next.
