If a Republican governor were to announce his selection of a running mate at one of the largest banks or corporate headquarters in downtown Minneapolis, or in the home office of MCCL or the NRA, it would draw some sharp editorial comment.
So I'll note here that I think it's odd and telling that Gov. Mark Dayton announced his choice for lieutenant governor at the AFL-CIO offices in St. Paul.
The lieutenant governor's office isn't just for political hacks, it's a high constitutional office and an important executive position. Making the announcement in the home offices of one of the DFL's core constituencies seems unnecessarily partisan, IMHO.
Maybe the impression is reinforced by the fact that Dayton chose his chief of staff for the job.
