This isn't all that surprising:
The Obama campaign is opposed to a Michigan re-vote mainly for reasons of politics. That's a descriptive truth I arrived at from reporting and talking to numerous sources within the campaign. It may well be true that there are legitimate grievances and obstacles to a new primary that the campaign has found -- indeed -- there appear to be some. Pointing out that the main reason for the opposition is political has pushed some readers to conclude that I have a pro-Clinton bias. Think what you wish.
I would say this, wouldn't I?, but Marc strikes me as one of the fairest reporters out there.
