David Weinberger is a Patrick supporter (he has the lawn sign to prove it) but he doesn't understand The Globe's endorsement.

...Doesn't that contradict everything newspapers believe about the value of a neutral point of view?...

I agree. Especially so, when the same paper lets fester a nasty dispute between two of the candidates by refusing to reveal what it knows -- and then endorses the third. A cynic might even say we were being manipulated.
