English to Spanish Social Sciences Other Politics

Se trata de un texto de ciencias políticas (de peronismo, en Argentina).
A lo largo de todo un capítulo el autor usa el término "stake" y no creo que "participación o interés" (que son las sugeridas en todos lados) sean una buena traducción en este caso.

"Because sectoral elites have tended to neglect party activity, they have acquired a reduced stake in the survival of electoral and legislative institutions".

"By investing resources in parties, by getting used to making demands through party channels, and by infusing parties with value, sectoral elites gain an instrumental stake in the survival of democracy¾over and above any principled commitment they may have to democracy itself."

"People who acquire a stronger stake in the survival of such institutions are, in turn, more likely to defend them when they are threatened."

"Weak ties between sectoral elites and parties have reduced the stake of such elites in the survival of the electoral and legislative institutions that parties require to be effective."
