General notes

In multi-member elections the bloc voting system was used. Voters could cast a vote for one or two candidates, as they chose. The leading candidates with the largest number of votes were elected.

In by-elections, to fill a single seat, the first past the post system applied.

Where a party had more than one candidate in one or both of a pair of successive elections change is calculated for each individual candidate, otherwise change is based on the party vote. Change figures at by-elections are from the preceding general election or the last intervening by-election. Change figures at general elections are from the last general election.

Candidates for whom no party has been identified are classified as Non Partisan. The candidate might have been associated with a party or faction in Parliament or considered himself to belong to a particular political tradition. Political parties before the nineteenth century were not as cohesive or organised as they later became. Contemporary commentators (even the reputed leaders of parties or factions) in the eighteenth century did not necessarily agree who the party supporters were. The traditional parties, which had arisen in the late seventeenth century, became increasingly irrelevant to politics in the eighteenth century (particularly after 1760), although for some contests in some constituencies party labels were still used. It was only towards the end of the century that party labels began to acquire some meaning again, although this process was by no means complete for several more generations.

Sources: The results for elections before 1790 were taken from the History of Parliament Trust publications on the House of Commons. The results from 1790 until 1832 are based on Stooks Smith. Where Stooks Smith gives additional information to the other sources this is indicated in a note.

Election results 1715–1832

As with most boroughs in the unreformed House of Commons, Amersham was uncontested at most elections. The only known contested elections after 1715 were those of 1728, 1735 and 1736.

• Death of Fermanagh 23 June 1717

• Choice of Drake to sit for Buckinghamshire

• Choice of Leveson Gower to sit for Newcastle-under-Lyme

• Death of Drake 26 April 1728

• (Note May 1728): Drake, the late MP, had been the owner of the largest interest in the constituency. His heir was a child and the anti-Drake element in the borough took advantage of the opportunity to contest the seat. Only about a third of the votes were cast for the challenger.

• (Note 1734): Thomas Bladen stood for the anti-Drake forces in the borough. The result again suggested that only about a third of the electorate opposed the borough's long term patrons.
• Death of Lutwyche 13 November 1734

• (Note 1735): The vote totals are unknown, but Gore won and no further contested elections took place during the remaining 97 years when the borough returned MPs.

• Appointment of Gore as Commissary General of the Musters (he was returned for Portsmouth)

• Death of Marshall 2 February 1754

• Death of Garrard
