On Wednesday morning, Nov. 9, 2016, Republicans awoke to learn they had won the lottery. Donald Trump had won the presidency by carrying Wisconsin, Michigan and Pennsylvania. All three states had gone Democratic in the last six presidential elections.

The GOP had won both houses of Congress. Party control of governorships and state legislatures rivaled the halcyon years of the 1920s.

But not everyone was jubilant. Neocons and Never-Trumpers were appalled, and as morose as they had been since the primaries produced a populist slaughter of what GOP elites had boasted was the finest class of presidential candidates in memory.

And there was this sobering fact: Hillary Clinton had won the popular vote. Her margin would rise to near three million, making this the sixth in seven presidential elections that the GOP lost the popular vote. Trump had cracked the Democrats’ “blue wall,” but a shift of 70,000 votes would have meant a third straight GOP defeat.

Seven months into the Trump presidency, the promise of a new Republican era has receded. It is not because Nancy Pelosi and Chuck Schumer have proven to be such formidable adversaries, but because the GOP coalition has gone to battle stations — against itself.

Trump has taken to disparaging Senate Leader Mitch McConnell for failing to pass health care reform, though the decisive vote to kill the bill came from John McCain, who, for his own motives and to media cheers, torpedoed McConnell’s effort and humiliated his party

And as Allan Ryskind writes in The Washington Times, McConnell is responsible for Neil Gorsuch being on the Supreme Court. Had Mitch not kept his troops in line to block a Senate vote on President Obama’s election-year nominee, Judge Merrick Garland, there would have been no vacancy for Trump to fill with Gorsuch.

What purpose is served by the coach trashing his quarterback — in midseason?

Undeniably, Congress, which the voters empowered to repeal Obamacare, reduce tax rates and rebuild America’s infrastructure, has thus far failed. And if Congress fails to produce on tax reform, the GOP will have some serious explaining to do in 2018.

As for Trump, he has fulfilled some major commitments and has had some major achievements.

He put Gorsuch on the court. He pulled out of the Trans-Pacific Partnership and the Paris Climate Accord. He persuaded NATO allies to put up more for defense. He approved the Keystone XL and Dakota Access pipelines.

Yet Trump is disliked and disrespected by many in his own party on Capitol Hill, and much of the Republican media proudly despise him.

And that form of bribery so familiar to D.C. — trashing one’s president at the coaxing of the press, in return for plaudits to one’s “courage” and “independence” — is openly practiced.

More critically, there are disputes over policy that again seem irreconcilable.

Free-trade Republicans remain irredeemably hostile to economic nationalism, though countries like China continue to eat our lunch. In July, the U.S. trade deficit in goods was $65 billion, an annual rate of more than $780 billion.

Even Cabinet members and Trump aides have let the media know they sharply dissent from Trump’s stand in the Charlottesville brawl.

The white working class that provided Trump his margins in the Middle West wonders why affirmative action has not been abolished.

What seems apparent is that the historic opportunity the party had in January, to forge a coalition of conservatives and populists who might find common ground on immigration, trade, border security, spending, culture and foreign policy, is slipping away.
