It is difficult to judge Harper and his government because there were different economic climates at the time, of which a Prime Minister essentially has to react to and can't really control per se. From what I recall, much of the economic policies in place were from the Martin/Chretien era. Harper didn't want to spend on stimulus until the Liberals and NDP started rattling their sabres (so some of the reactions of the government were opposition initiated and not preferred by Harper).

I think the main point here is that the Liberals did well, at least economically during their last run. The Conservatives don't necessarily need to be attacked... the Liberals look good in that one facet on their own merit. There are other completely valid reason to be disappointed with their previous governments though.
