Graph yikes

Ed Hollett posted the above graph on Sir Robert Bond Papers today; it shows how voter preference in Newfoundland and Labrador has shifted since Confederation. The data include results of each federal election, with the last set coming from the CRA quarterly regional poll released last week. (Ed, for those not familiar with his politically minded blog, views things from the big Liberal tent, incidentally.) Ordinary warnings - the margin of error, the snapshot in time - apply, but it is an interesting visual presentation.
