"First-Past-the-Post" (Plurality) Systems are Inferior to

Transferable Vote (Preferential) Electoral Systems

A "First-Past-the-Post", or plurality, electoral system results in the election of a candidate that can be supported by less than 50% of the voters, with the remaining voters preferring somebody else.

 

That unsatisfactory and undemocratic outcome is avoided with the Transferable Vote (Preferential Voting), where the ballot-papers of those that voted for the least well-supported candidates are examined successively and transferred to remaining candidates until one of those remaining candidates receives an absolute majority of the votes cast, i.e. more votes than the combined votes of the remaining candidate or candidates whose votes have not been needed to produce such a majority. Australiaís House of Representatives has been elected by preferential voting since the Commonwealth Electoral Act 1918 was passed in its original form in that year.

 

"First-past-the-post" used to fill multiple vacancies:

 

Various arrangements are possible here, and each of them has proved to be unsatisfactory, compared with the quota-preferential alternative.
