Frankly, he's back among his partisan peers.  I seriously doubt he's going to walk into any newsroom in Michigan and automatically increase the liberal toxicity permeating the place.  Outside of Hillsdale or the Detroit News maybe.

This does raise an interesting question about disclosure and journalistic ethics, though.  Does the paper have a responsibility to identify the man everytime one of his columns is printed?  To let their readers know who he is and what he does for a day job?  

On the same tack, asking readers to keep an eye out for liberal bias in his reporting is hardly sufficient.  His ideology can and almost certainly WILL affect WHAT he covers, WHEN he covers it and HOW he covers it.  He could submit a straight fact-sheet on a benign issue B while completely ignoring an issue A that was equally newsworthy but would have been a malignant tumor on the spine of Michigan Democratic Party.  Depends on how he wants to handle a given assignment.  

Not sure anyone would argue that the MSM has a narrative and they avoid anything that doesn't fit that narrative.  How much more irresponsible to leave the creation of that narrative in the hands of a hard-line extremist like EB?
