The Senate confirmed David Brat — the economics professor who shocked Washington by primarying House Majority Leader Eric Cantor in 2014 — as the next U.S. ambassador to Australia Friday, putting a swamp-draining populist in charge of one of America's most consequential relationships in the Pacific.

The 51-47 party-line vote, part of a Republican push to clear 74 nominees before the August recess, sends a man the Beltway class once dismissed as a nuisance to a post that sat empty for 18 months after Joe Biden's ambassador Caroline Kennedy departed in November 2024. Australia is a key partner in the $370 billion Aukus submarine deal and a target of Trump's new 12.5% tariffs. Brat's arrival coincides with the 75th anniversary of the Anzus security treaty — and with growing Australian disquiet about whether that deal delivers what was promised.

Brat's path to Canberra runs straight through the swamp he spent years promising to drain. In 2014, he pulled off what The Guardian described as a sweep into Congress by defeating Cantor in a Republican primary — a win nobody in the consultant class saw coming. He won the general, served two terms, then lost his seat in 2018 to Democrat Abigail Spanberger, now Virginia's governor. After Congress, Brat landed as vice-president of business relations at Liberty University.

Time magazine branded him a "Tea Party professor" and an Ayn Rand enthusiast. In a 2011 paper, Brat argued that capitalism and Christianity should merge, writing: "If we all did the right thing and had the guts to spread the word, we would not need the government to backstop every action we take." That's the kind of talk that makes K Street uncomfortable — and apparently still does.

The Guardian made sure to flag that Brat "claimed US intelligence agencies conspired to remove Trump from office," framing it as a mark against his credibility. Reuters, by contrast, buried Brat in a list of 11 confirmed ambassadorships and focused on procedure. The AP outlets covering the same vote barely mentioned him at all, leading instead with FEMA. When the press consensus is to treat a populist's skepticism of intelligence agencies as disqualifying while ignoring his actual record, that tells you something about whose interests they're protecting.

Australian Prime Minister Anthony Albanese took the diplomatic route in April: "We respect the sovereignty of countries to put forward ambassadors just like we expect our choices to be endorsed." Translation: Canberra will deal with whoever Washington sends.

The confirmation lands at a tense moment. Trump hit 54 economies, including Australia, with 12.5% tariffs in July over what the U.S. claimed was a failure to enforce prohibitions on goods made with forced labor. Australia's trade minister Don Farrell called for the tariffs to be removed, citing the free-trade agreement. Meanwhile, the Albanese government announced in May it would buy three second-hand American nuclear submarines under Aukus instead of the original mix of two used and one new. Former Labor cabinet minister Ed Husic said the change meant "we are not going to get the deal that was promised to us" — a $370 billion question for Australian taxpayers and American shipyards alike. Every dollar committed overseas is a dollar that competes with domestic needs. Americans deserve to know what the return is.

Reuters reported that Brat's confirmation fills a fraction of the more than 100 vacant ambassadorial positions after Trump recalled dozens of career diplomats appointed under Biden. The vote was straight party lines — every Republican in favor, every Democrat opposed. When both parties agree, the public usually gets sold out. When they split this cleanly, it's worth asking what the fight is really about.

The D.C. class said Brat couldn't win. He won the primary. They said he couldn't hold the seat. He won the general. Now they say he can't represent America abroad. The question isn't whether David Brat can handle Canberra — it's whether a man who built his career arguing the government shouldn't backstop every action will push that conviction on the world stage, or whether the swamp has a way of swallowing even its loudest critics once it gives them a title.
