Personal Votes: the 2016 Australian Federal Election
Adopting a technique favored by Peter "Mumble" Brent, we compute a House candidate's "personal vote" as the difference between their 1st preference vote and their party's share of 1st preferences cast for Senate in the candidate's division. This is easily implemented given the results files provided by the AEC, as the following code demonstrates. Estimates of personal votes are produced for over 400 Coalition, Labor and Green House candidates in the 2016 election. - For Coalition incumbents in NSW in 2016, the average difference between House and Senate vote was **8.2 percentage points**; in Wentworth this difference was **9.3 percentage points**. - Turnbull's apparent personal vote in Wentworth is not especially large relative to the apparent personal votes of other NSW Coalition incumbents in 2016. - Wentworth is more "distinct" with respect to its large House and Senate votes for the Coalition.
