Could you please cite, quote or link to Marhsall's "strong endorsement of Lieberman."  I don't remember that one.  But maybe it was there.

Also, it's pretty clear he's acknowledged he was wrong on the invasion of Iraq.  It's not as good as being right in the first place, but it's more than a lot of liberal hawks can say, to say nothing of those on the other side.

This is no brief for his endorsement of Rosenberg.  I just don't think you're being fair to Marshall.
