Mike Lofgren, a former congressional staff member who served on the House and Senate budget committees, first came to national attention in 2011 with his powerful essay Goodbye to All That: Reflections of a GOP Operative Who Left the Cult. Lofgren has been a regular contributor at Truthout since then.

Lofgren has another must-read op-ed at the New York Times. Reagan’s ‘Party of Ideas’ Is Down to Just One: Tax Cuts:

It is a sign of our slide toward banana republic status when the president of the United States, leader of the world’s foremost democracy, publicly brands Democrats who failed to applaud his State of the Union address as un-American and treasonous. The largely partisan audience was fine with it.

What has become of the Republican Party, which I once served on Capitol Hill and which I now consider a dangerous extremist movement on a par with the ruling Fidesz party in neo-fascist Hungary? Where did its principles go? What became of Ronald Reagan’s “party of ideas”?

One by one, those ideas were tossed aside for expediency and power — except the tax cut. A time traveler from the Reagan era would no longer recognize the Republican Party, but most Republican politicians feel no embarrassment supporting policies they once condemned.

Since World War II, Republicans have styled themselves the party of national defense. Yet under President Trump, they have unsettled our alliances and professed a strange new respect for Vladimir Putin.

The Republicans were once the party of global free trade, a system with major flaws but one that requires reform, not ham-handed overthrow. Yet the president believes he can bully longtime allies and force them to accept bilateral trade deals on his terms. A likely result is that the allies associate with trade blocs like the European Union or the revised Trans-Pacific Partnership so that they can better resist his bullying.

Despite Mr. Trump’s protectionist talk, the offshoring of jobs has increased slightly during his presidency. And the latest figures show the trade deficit rising to a nine-year high, with imports from China and Mexico, his main boogeymen, reaching record levels. His tariffs on Chinese solar panels, supposedly to assist our domestic producers, will cost an estimated 23,000 United States jobs.

An enduring caricature of the old-time Republican is the penny-pinching deficit hawk. In truth, this philosophy was honored mostly in the breach, as the Reagan and George W. Bush presidencies revealed. But it was alive enough that George H. W. Bush, channeling the fiscal prudence of Dwight Eisenhower and Gerald Ford, sacrificed a second term to achieve deficit reduction.

Under Mr. Trump, who has extolled leveraging other people’s money while declaring that debt is good, the party is no longer even half pregnant. His tax act, passed exclusively with Republican votes in both the House and the Senate, increases the national debt by over a trillion dollars and awards 62 percent of its monetary benefits to the richest 1 percent of Americans.

Paul Ryan, the House speaker, sees the tax act as a bonanza for the working stiff: He tweeted that a public school secretary would see a whopping $1.50 a week extra in her paycheck. It’s touching that the secretary can now afford an extra McDonald’s coffee every week, but the deficit, thanks partly to the tax cut, is projected after years of decline to explode to a trillion dollars annually.

Tax cuts, regardless of the deficit, are an obsession with Republicans and a source of shameless hypocrisy. During the recent shutdown crisis, the House Freedom Caucus balked at a deal to avert an impasse because it contained additional domestic spending, while in the Senate, Rand Paul of Kentucky held up the vote because the spending creates debt that threatens “the livelihoods of our children.” Yet the senator and every single Freedom Caucus member enthusiastically had voted only a few weeks before for a fiscally irresponsible tax bill.

Republicans were once the party of conservation and the environment: from Abraham Lincoln, who set aside Yosemite for what later became a national park, to Theodore Roosevelt, preserving 230 million acres of public land, to Richard Nixon, who signed the Clean Air Act and created the Environmental Protection Agency.

Now the E.P.A. is being systematically gutted. Its administrator, Scott Pruitt, has named as chairman of its science advisory board a person who criticizes the E.P.A.’s standards for exposure to mercury (a neurotoxin causing severe brain damage) and believes ozone pollution rules are unnecessary because Americans spend most of their time indoors. Another of the board’s “alternative” scientists is a man who has stated that “modern air is a little too clean for optimum health.”

Republicans always counted themselves as strong supporters of law and order. Whenever a crime bill was considered in Congress, I used to joke with my colleagues that any minute, a Republican would offer an amendment proposing the death penalty for jaywalking. But the president’s high-decibel smear campaign against the professionals of the F.B.I. destroys the party’s pretense of being a friend of law enforcement, as does the administration’s dismantling of the Consumer Financial Protection Agency and its rules against consumer fraud. The fact that Mr. Trump and his senior appointees are scofflaws regarding conflict-of-interest statutes does not enhance their reputation as straight arrows.

So what do Republicans have left? The tax cut, the sole important legislation from the Republican Congress, shows that catering to its rich contributors is the party’s only policy. The rest of its agenda is simply tactics and trickery.

As the party has become unmoored from positive belief, it has grown manipulative, demagogic and contemptuous of truth. This was foreshadowed in 2004 when a senior adviser to George W. Bush boasted that “we create our own reality.” It has culminated in the president’s counselor Kellyanne Conway’s appealing to “alternative facts,” meaning lies, on behalf of her boss, who has made an average of 5.6 false or misleading claims a day since his inauguration.

Today’s Republican Party is incapable of honest and coherent governance, with “right” or “wrong” reduced to a question of whether it helps the party. Its agenda is little more than institutional vandalism and a thumb in the eye.

A few Republicans protest the president’s disgraceful behavior, but never in a way that matters. Senator Jeff Flake of Arizona has become famous for sanctimonious speeches denouncing the latest outrage, but he votes with machine-like consistency in favor of the president’s destructive agenda and unqualified nominees.

Ultimately, the party’s spiritual sickness isn’t about Mr. Trump. Eight years ago, did Republican officeholders shut down the nonsense that Mr. Obama was a secret Muslim? For that matter, a quarter-century ago, did they quash the idiotic charge that the Clintons murdered Vince Foster?

Donald Trump merely aggravated what has long been building up in the party of Lincoln. In 2011, when House Republicans threatened to drive the government into default to extort political concessions, I left the party. Seven years later, it has become so extreme that I fear it is endangering the stability of the republic.

The GOP is a danger to the Republic … let that sink in. Then pledge to resist the GOP and to commit yourself to working to defeat this threat to our country.
