That would be a dream come true, but it would have one interesting side effect: how would you want the NDP as the official opposition, since they'd probably snare votes off the left wing...it would also create a gaping hole among the 'progressives' and at center-left, since their choices would be the right-wing Conservatives, the left-wing NDP, a fringe party or staying home...
That Saskatchewan PC Party implosion may have had a silver lining - it opened the door for the new Saskatchewan Party, which is really their version of the Conservative Party - without the word 'progressive' and mostly pure conservatives...
