One of the unknowables was whether Clinton's people had any idea what they were doing for this campaign. It's pretty clear now that they did. Forgive me for having been a bit dubious, but the 2008 Clinton campaign was a lesson in what not to do and who not to hire. I think there have been some dubious efforts in the broader Clintonverse, but just about everything coming from Clinton and her campaign has been about right.
Easy to say that if they appear to be winning, of course. It's a bit of a problem in politics, that the winners can claim to be geniuses simply by virtue of winning when it's possible that in a slightly different timeline they'd be losing, but this couch critic has had few complaints.
