Contributor: The GOP is collapsing under Trump’s loyalty tests

Americans always say they want politicians with backbone — men and women of principle who will stand up for what they believe in, even when it’s unpopular.

And every so often, the American people prove their commitment to this noble aspiration by firing anybody who actually tries it.

Take Republican Rep. Thomas Massie, who just lost a reelection bid by double digits after President Trump’s affiliated committees dumped enough money into Kentucky to purchase, well, Kentucky.

Massie committed the cardinal sin of modern Republican politics: He behaved as though Congress were a coequal branch of government instead of the warm-up act before a Trump rally.

He bucked Trump on spending, Iran and — in what apparently qualified as political suicide — whether or not to release the Epstein files. For this display of independent thought, Massie was summarily retired by what can only be described as the Trump cult (formerly known as the Republican primary electorate).

Before anybody accuses me of hyperbole, consider the remarkably revealing example presented recently on the New York Times podcast, “The Daily.”

At a town hall in Burlington, Ky., one voter explained to Massie that Trump is basically omniscient.

“As I see it,” the voter said, “the one person in the whole United States, maybe the world, that understands everything and has input to everything is Donald Trump.”

Not content with mere earthly wisdom, Trump also possesses universal awareness, superior intelligence and perhaps even low-level clairvoyance. The voter continued that Trump “gets more information, more meetings, more everything” than anybody else in government.

When Massie noted that Trump opposed releasing the Epstein files, the man calmly explained that if Trump changed positions, “there was a reason” — one too profound for ordinary mortals to comprehend.

Massie’s reply deserves to be bronzed and mounted over the entrance to the U.S. Capitol: “I don’t give anybody but God that kind of trust.”

Unfortunately, for a large portion of the Republican electorate (about 55%, based on the Kentucky primary results), those words constitute sacrilege against their earthly savior.

As South Carolina Sen. Lindsey Graham cheerfully boasted on NBC’s “Meet the Press” on Sunday, “This is the party of Donald Trump.” Which is true in much the same way North Korea is the party of Kim Jong Un.

The one ironic twist in all of this is that Americans finally managed to punish somebody over the Epstein files — only it turned out to be the guy who wanted them released.

There’s American justice for you.

Massie isn’t the only Republican currently being fitted for concrete shoes. Trump also helped finish off Louisiana Sen. Bill Cassidy, whose unforgivable crime was voting to convict Trump during the impeachment trial following Jan. 6. And Trump has endorsed controversial Texas Atty. Gen. Ken Paxton over incumbent Sen. John Cornyn, which in today’s GOP primary environment is roughly the equivalent of finding a horse head in your bed.

Now, to be fair, Cassidy and Cornyn are no Massie, who openly opposed Trump and paid the price standing upright. Cassidy and Cornyn demonstrated brief moments of independence, only to spend years vainly performing political interpretive dance routines in hopes of regaining Trump’s favor.

Still, there may be a silver lining here for students of political irony.

Trump’s endorsement of Paxton will force Republicans to spend enormous sums defending a deep red state that would ordinarily require little more than a campaign sign and a pickup truck.

Meanwhile, Trump is creating resentful lame-duck Republicans in Congress who now possess the most dangerous attribute in politics: nothing left to lose.

But the broader message is unmistakable. Trump wants Republicans to understand that disagreement will not be tolerated. No criticism. No distancing. No independent branding.

The party line is whatever Trump said five minutes ago, amended by whatever he says five minutes from now. By now, everyone knows this to be true.

Which would be excellent news for Trump, if not for one small complication: The rest of the country appears to be tiring of his act. Recent polling shows Trump’s approval slipping to 37%, while Democrats gain major ground, surging to a +11 on the generic congressional ballot.

Trump, it seems, has created a situation in which Republicans can either oppose him and be destroyed in a primary, or they can embrace him and risk losing the House and the Senate in November’s general election. It’s the old “damned if you do, damned if you don’t” conundrum.

The point is this: With the midterms approaching, Trump is making sure Republicans are ensnared in the gravitational pull of his unpopularity.

That may satisfy the president’s desire for complete loyalty. It may also hand Democrats control of both chambers of Congress.

Trump is settling all family business this week, by purging those pesky disloyal Republicans. Only time will tell whether he’s also purging America’s non-Republican “swing” voters, as well.
