In a multi-party political environment, the First-Past-The-Post electoral system may mitigate polarisation

In this post, Niall Hughes argues that FPTP electoral system performs much better in the context of multi-party politics. Crucially, in a general election a voter’s preferred candidate will depend on the results in other constituencies. As a result, when three parties compete in a general election and voters care about national policy, the problem of polarisation under FPTP is mitigated.
