One influential theory predicts that in single-member districts

Question

Quizplus · Accepted Answer

The theory referred to is the Median Voter Theorem, which suggests that in single-member districts with plurality voting systems, candidates will move their policy positions towards the center of the political spectrum to appeal to the median voter, who is presumed to be centrally located in the ideological spectrum. This is because capturing the median voter is crucial for winning the election, as it secures a candidate votes from the center of the political spectrum, potentially outmatching opponents who might position themselves more towards the ideological extremes.
