In this article, a model is built to the electoral conflict.A hypothetical example is analyzed based on the confrontation between four political trends, identified, on the basis of the position regarding their position before the composition of public spending, as: liberal, conservative, developmentalist and socialist.The basic hypothesis is that parties seek voter approval and that voters choose the parties that agree with them on a number of topics on which parties and voters can take one of two opposing positions.Each party must seek to have the electorate agree with its position on each issue.And voters decide assessing the likelihood that each party will take their same position on the issue.The probabilistic modeling and the composition of criteria with interaction open here a new perspective for this type of analysis.In particular, subsidies are presented for strategies in which parties give up their own alternatives to unite around other more viable ones, reducing the number of conflicting alternatives.
