Condorcet’s Counter Example A is preferred to B by One & Two B is preferred to C by One & Three C is preferred to A by Two & Three Majority rule can yield a cycle over the choices!
Agendas • A versus B - the winner against C • A versus C - the winner against B • B versus C - the winner against A

Latent Ideological Space 1 Issue positions cluster: If I know what you think on defense and environmental policy, I can guess what you think of school lunch subsidies. 2 Shared meaning: This clustering phenomenon is not purely atomistic, so that ideological positions such as “liberal” and “conservative” have similar meanings to different people. 3 Constraint: If the effective space of political conflict is “ideological” in the sense above , the strategies of candidates (and hence the choices for voters) in the policy space are highly constrained.
Communication: To provide voters with a message they can understand and use to make choices, parties must simplify their message. Because only broad statements of principles can be used in advertising and position-taking, the latitude for more subtle distinctions and differences is highly circumscribed. Ideological positions emerge for solving problems of uncertainty and lack of information. The space evolves as groups struggle to alter the status quo.
