Figure 1 Illustrates an Election in Which There Are Seven

Figure 1 illustrates an election in which there are seven voters (A, B, C, D, E, F, G) arrayed along a single left-right issue dimension that runs from 0 (most left) to 10 (most right) . Each voter is assumed to have a single-peaked preference ordering over the issue dimension and to vote for the party that is located closest to her ideal point. The voters are participating in a majority rule election in which there are two parties, P1 and P2, competing for office. These parties can be thought of as "office-seeking" parties since they only care about winning the election and getting into office.
