On 8 February 2026, Portuguese voters will decide a presidential runoff between António José Seguro, backed by the Socialist Party, and André Ventura, leader of the far-right Chega. The argument I advance here, however, is analytical rather than electoral: that this election crystallizes a confrontation between two models of democracy – one liberal, rooted in the constitutional settlement that emerged from the 1974 revolution, and one illiberal, that treats constitutional constraints as obstacles to the expression of popular will rather than as safeguards of it.
