 abstract={The entry problem in a political race for a two-party system is considered in the paper. We assume that two parties are displayed along one ideological dimension and the approval voting is used. We discuss chances for winning of any new enterer. We formulated necessary and sufficient condition for win of any new enterer in terms of expected value of number of votes s/he receives and in terms of sets of voters with the same preferation order.},
