ETA - switched the link (google his Facebook page if you want to see his full post).

I don't like some of Olson's policies he's put forth and would prefer the seat to flip blue. But at the same time, he's a good guy and has been fair and civil most of the time. His link mentions his mother-in-law's health, but I've also heard rumors about his health not being amazing. I hope everything works out for him in the future.
