If politics is "the art of the possible," then we're going to have to accept that Canadian voters are not yet informed enough to see that both the Liberals and the harpercons are useless, and we're going to have to play the hand that's been dealt to us.
ETA: I added this in the comments section:
I can't stand the Liberal Party but it isn't going to go anywhere and many of its supporters (especially the bloggers i read) are decent people. By all means, if we have to get rid of Iggy to do this, maybe they could find another Stephane Dion, we should do this. As intolerable as the empty-rhetoric Liberalism of Paul Martin was, it is even more intolerable that we live in a country where stephen harper is within sight of a majority government.
