According to a paper released today (pdf) by Andrew Leigh and Amy King, better-looking election candidates receive slightly more votes than unattractive election candidates.
Being good-looking is not, however, always a benefit in politics. In the beauty ratings, Ross Cameron did considerably better than most other male politicians. Unfortunately, perhaps, this also made him attractive to women other than his wife, eventually leading Genevieve Cameron to chuck him out of the house during the 2004 election campaign. Julie Owens, rated as OK by the beauty panel, took his place in Parliament.
It’s hard to imagine too many women throwing themselves at Australia’s least-attractive MP, Labor’s Dick Adams, which should save him from at least one type of political scandal.
