So that was (almost) the 2010 Federal Election. Independent candidate Andrew Wilkie surprisingly won Denison. I've plotted the two party preferred vote totals for each of the polling booths, below, using data from the AEC, red for Jackson and yellow for Wilkie. It's almost as though there are two electorates; a Labor stronghold in the north and a swarth of Wilkie territory from Creek Road to Kingston.
