The diploma divide is replacing wealth and income as the primary division in western politics. By Samuel Thawley in The Spectator.
Many Western democracies are going through the same political realignment. The diploma divide – the sorting of electorates by education, specialisation, and institutional disposition – is replacing wealth and income as the primary cleavage. Australia arrived later. However, it will resolve faster – with preferential voting as the accelerant rather than stabiliser. The structural earthquake here will be shorter, sharper, and – if the data hold – largely complete in the span of the next two to three elections. …
Trump saved the Republican Party:
The standard narrative across the Western commentariat — left and right — is that Donald Trump degraded the Republican Party. He trashed its norms, alienated its professionals, and turned it into a personality cult. This is the story told over glasses of wine in Toorak and over flat whites in Balmain.
The structural story is the opposite.
Almost every centre-right party in the Western world today is facing the same centrifugal force: the diploma divide is tearing its coalition apart. The professional wing — the university-educated, socially progressive, economically liberal urban voter –is departing in one direction. The non-graduate wing — culturally conservative, economically interventionist, institutionally hostile — is leaving in the other. The leaders have failed to hold both simultaneously because the interests have now become too disparate. …
The Coalition in Australia is losing voters simultaneously to teal independents on its left and One Nation on its right.
The only traditional, majority right party to survive has been the Republicans in the US. The reason is obvious: Trump’s arrival. His structural function was not to ‘ruin’ the Republican Party but to resolve the tension destroying every comparable party elsewhere. He captured the party machinery via the presidential primary system, fused the populist insurgency into the major party, and expelled the professional wing rather than allow the non-graduate wing to split itself off. …
He didn’t persuade the Republican machine – he bypassed it, going directly to voters in a system which permitted exactly that. Westminster systems do not have open primaries. The preselection process is the institutional gate.
Trump’s Republicans are unique. Everywhere else in the West, the main right wing party is dying as it splits:
The leader who best understands the emerging electorate is precisely the person the machine cannot tolerate, because the qualities making him or her effective outside the party — directness, conviction, disruptive energy — are the qualities threatening the machine’s internal equilibrium. …
Almost no party instance across the Anglosphere since the start of politics has succeeded long-term by expelling the rebel or coopting the outlier. … The institution almost always fights back and the propagation ultimately fails. …
Trump is the sole possible counterfactual. He succeeded in capturing the party because the primary system exists — and this has given him a particular strength that earlier hopefuls have not enjoyed. However, the question remains for 2026 and 2028 — and for the long-term: will the Republican party and its leadership continue his legacy, or will Trumpism join the Thatcher-Abbott class, and Trump see all his work undone? …
One Nation may become the main conservative party in Australia:
The addressable market is defined not by self-identity, not by geography, but by status or social position. It is the non-graduate, the tradesman, the self-employed contractor, the outer-urban family priced out of the inner ring, the regional voter who has watched institutional trust drain out of every authority that used to speak for him or her. The constituency is not a niche – it is now the largest single voting bloc in Australia that no establishment party currently treats as its primary constituency.
One Nation’s ceiling is status-bounded and diffuse. … So is Reform UK’s in Britain. These are once-fringe parties whose potential constituency is larger than the party they are seeking to displace because the group they represent is now bigger than the established electorate that the incumbent, devotedly centrist, party, has decided to prioritise. …
What’s in a name?
The National Party, as one of the longest-serving political organisations in the country, has the benefit of incumbency. It also has the benefit of a name that most precisely fits the emerging voter demographic.
The Liberal Party has a complicated name, reflecting an ideology that no longer aligns well with the electorate it needs to win.
Meanwhile, One Nation — whose name enjoys a solid historical pedigree — sounds more like a multicultural welcome and, ironically, a certain openness to immigration.
The Nationals have the potential:
Moreover, the National Party is already well-positioned to leverage distinctive elements of the Australian electorate that mix hints of the MAGA movement in America and the Reform movement in Britain. …
The only realistic opponent One Nation faces is the National Party, but — as the defections of Barnaby Joyce in one direction and Jacinta Price in the other both hint — the party has decided not to fight. …
The likely future of the Australian Liberal Party:
Under Australian preferential voting, the Liberal Party’s realistic forward path might be more like Germany’s SPD under repeated grand coalitions: declining by five to nine primary-vote points in each grand-coalition cycle, never quite collapsing, never quite recovering, becoming a party whose continued existence is structurally necessary to the system but whose paradigm-carrying role has ended.
The Teals have removed the professional-class left flank. One Nation is removing the non-graduate right flank — something that the Nationals could do as well if they wanted. What remains is a rump constituency: economically liberal, socially centrist, institutionally attached, declining as a share of the population in every election cycle.
