If there is only one more reason allowed to consider moving to a city manager form of government, this is it.  

I get it:  Portland likes to be different.  It's edgy, it's cool.  Keep Portland Weird.  The largest city in the US with this form of city government and you actually think you are ahead of all others?  Electing trust fund babies and nurses to lead departments with multi million dollar budgets, and yet no practical experience in managing either people or money, is not being unique.  It's being stupid.
