Born and raised in the iconic Carlist Aragón dynasty, Jesús was from his childhood growing accustomed to regional and national party leaders visiting his family home.
As a teenager he was active in Carlist juvenile organizations, and in 1912 he rose to leader of the local Agrupación Escolar Tradicionalista.
At that time he was already active beyond his native Aragón, e.g. when leading a group of Navarrese youth during pilgrimage to the Zaragoza sanctuary of Virgen del Pilar.
In the 1910s Carlism was suffering from conflict between the claimant, Don Jaime, and the key party theorist, Juan Vázquez de Mella; the Comín family, though like de Mella assuming somewhat Germanophile positions during the Great War, remained loyal to their king.
Jesús career in the party ranks was boosted when his uncle assumed leadership of Comunión Católico-Monárquica; the same year he entered Comité de Acción Jaimista, a loyalist body working to mobilize support for the pretender.

In 1919 Comín took part in works of the grand Jaimista reunion named Junta Magna de Biarritz, an assembly intended to provide the movement with a new momentum following the Mellista breakup.
Though the gathering was massively attended, his taking part demonstrated Comín's growing position in the party ranks.
In 1920 he tried his hand when running for the Cortes from the South Aragonese district of Daroca, presenting his bid as a Jaimist and Agrarian candidate.
He lost to a conservative rival and appealed, accusing his counter-candidate with corruption; the charge was dismissed.
He did not take part in the last electoral campaign of Restauración in 1923, as the Jaimistas agreed they would abstain from what they considered corrupt democracy.

Advent of the Primo de Rivera dictatorship brought political life to a standstill, with all political parties dissolved.
There is no information on Comín's political activity during the mid- and late 1920s; he is listed neither as engaged in Carlist organizations nor in the primoderiverista structures; when noted in the press, it was rather due to his university engagements, activity in numerous Catholic associations, like Caballeros de Nuestra Señora del Pilar, or organizing sport events, e.g. a lawn tennis tournament in Zaragoza.
Upon the fall of dictatorship and re-emergence of Carlist political structures in 1930 Comín was for the first time noted as member of the Aragón party executive, Junta Regional.
Some authors claim that during dictablanda he was not adverse towards the new military regime and tentatively agreed to take part in "organized" elections for the Cortes, planned for 1931; he would stand in Daroca again.
Nothing came out of these plans as the monarchy collapsed and the Republic was declared.
