The non-acceptance by the majority of the population of Ukraine of the idea of elections during a full-scale war is a forced prolongation of the legitimacy of existing state institutions. Ukrainians understand all the risks of such elections for the political system under martial law, agreeing to the norms of legislation and compliance with democratic procedures. At the same time, a sufficiently significant number of the population is forming, which does not share the monopolization of power during the war by one political force. Accumulation of political issues, which will be expressed in the post-war period, will become a significant challenge for the political class of Ukraine. The low level of trust in existing political parties and the growing demand for new political forces can become a favorable background for the spread of anti-elitist ideas of populism. In public opinion, there is a demand mostly for politicians from the military environment and to a lesser extent from expert and civil sectors, intelligentsia, and volunteers. Reconstruction of the post-war economy will require non-standard solutions, in particular, optimization of expenditures in the social sphere and maximum liberalization. Several innovations will not have support in the mass consciousness. In particular, Ukrainians are mostly in favor of free medicine and education, a ban on the sale of land to foreigners, and assigning responsibility for increasing people’s incomes to the state, not to the individual. The lack of financial resources after the end of the war can accelerate the growing social deprivation. The combination of these potentially conflicting attitudes with a high level of antagonism and intolerance to a different political point of view can be skilfully «warmed up» by populist forces.
