Seems there is another "strategic voting" site that ran during the 2004 and 2006 elections as well. Whack the PM from The James Gang has you clicking on the leader you least like, then your postal code, and it recommends you who to vote for in your riding to vote against that party.
I find the whole thing both silly and dangerous as I've written before, but I am curious how much influence these types of sites will have. There is far too much focus on the "leaders" in federal elections from the mainstream media, and part of the beauty of new media should be that we get more information about our own riding (who we are actually voting for) and make better voting decisions. Will people actually take their advise? Will the best candidates be blocked out of the election based on people making their entire choice based on the leaders and historical voting patterns?
