Define the term multiple decision makers - Strategic Voting
The following lines, from Austen-Smiths' (1986) clarify the position quite succinently. He writes, 'so in elections, rational policy oriented voters will take in to account not simply the particular issue positions announced by candidates contesting their districts but also the likely policy outcomes to emerge from legislature, conditional for electing one or the other of these candidates.
This in turn will depend on voter's expectations regarding both coalition formation among elected officials and the bargaining process within such coalition. Rational office seeking candidates will take account of these voter distributors in choosing a policy position with which to contest an election. Such strategic voting comes also in cases where there are multiple decision makers at a single stage and franchise differs across the choice of these decision makers.
It may also take place within legislature, a phenomenon known as 'logrolling' which refers to an agreement between two or more voters for mutual support requiring each to vote against his preferences for some issue. In this way even those policy agenda gets adopted which would have been rejected had the voters voted sincerely.
