The most significant threat to a political ideology comes not from the opposing party, but from the 'lunatics' on its own side. These extreme factions can make the entire group appear foolish and unreasonable, doing more damage to their credibility than any opponent ever could.

Australia's traditional Liberal-National conservative coalition faces an existential crisis from two directions. The populist One Nation party is siphoning off its rural base, while climate-focused "teal" independents are capturing its affluent, urban strongholds. This dual erosion makes a unifying strategy nearly impossible.

The appeal of a populist leader lies in their rejection of traditional political norms. When the electorate feels betrayed by the established "political class," they gravitate toward figures whose rhetoric is a deliberate and stark contrast, signaling they are an outsider.

A savvy political strategy involves forcing opponents to publicly address the most extreme statements from their ideological allies. This creates an impossible purity test. No answer is good enough for the fringe, and any attempt to placate them alienates the mainstream, effectively creating a schism that benefits the opposing party.

South Korea's mainstream conservative party is increasingly influenced by a loud, far-right fringe. This group, composed of online commentators and YouTubers using MAGA-style tactics, has demonstrated the power to mobilize the party's base and dictate its leadership choices, effectively marginalizing moderate voices.

Japan's ruling LDP selected Takaichi Sanae, a leader with a brash, populist aesthetic, not to upend the system but to co-opt populist appeal. This strategy aims to fend off genuine anti-establishment challengers and re-establish the party's grip on power, demonstrating a novel approach to maintaining the status quo.

In politics, the perception of strength and decisiveness can be more electorally powerful than being correct but appearing weak or compromising. This principle explains why a political party might maintain a hardline stance that is unpopular, as the image of strength itself resonates more with voters than the nuance of being “right.”

Instead of isolating Nigel Farage's populist movement, the UK's Conservative Party adopted many of its core tenets, such as Brexit and anti-immigration stances. This strategy of assimilation blurred ideological lines, making a future coalition with Reform UK more palatable internally.

The conventional wisdom that moderate candidates are more electable is a myth. Elections are won by turnout, not by appealing to the median voter. A polarizing figure who excites their base will often win by a larger margin than a moderate who fails to generate enthusiasm.
