The WSJ and other major publications have a vested interest in brokering access by tailoring their coverage to be friendly to those in power. They are largely responsible for setting the agenda and tone of issues during an election.

Given these two factual statements... The stated stance of the current administration was to downplay the impact and scale of economic hardship, and the role of major media outlets during an election is to set out the agenda and issues to be debated during an election period...
I think it clearly follows that the WSJ had a vested interest in providing one perspective on the economy before and during the election, and now that this period is over, they can provide a different perspective more aligned with the perspective of the working class, and less aligned with the perspective of the incumbent administration.
