A lot depends on where you are.
Several places I’ve been, people switch from pd to so with each change of the elected officials.
Right now we have 4 running for sheriff here. All republican.
Two have little to no chance, if the incumbent gets it, nothing will change.
The challenger gets it, there will be a shake up and several pd guys will switch over.
But we have a good group of guys on both departments.
And no gang mentality in either group. Regardless of what some may think.
