By examining the Manifesto Project data for post-transition Chile, we show growing convergence in the electoral competition strategies between the centre-left and centre-right coalitions. While the former is characterised by inertia, the latter is marked by gradual yet relentless programmatic moderation. To interpret these results, we rely not only on theories of salience and party adaptation, but also on the cartel party thesis. This contribution reinforces the findings of increasing literature on post-transition Chile that reveals growing collusion between the mainstream left-wing and right-wing coalitions, which have increasing difficulties channelling demands emanating from below and therefore providing adequate political representation.
