If my theory of revenge is right, I wouldn't be surprised if Washington is at the top of his list. But the Preds GM job opened up first and they're also on the list so why not check things off as they present themselves?
Yes, with his performance in Nashville, this decision could hurt his chances of getting hired as the Caps GM to exact his revenge, but terrible GMs get hired by new teams all the time, just like terrible coaches. He might need to make a stop somewhere else and show that he's actually semi-capable to re-establish his cover story, and then take the Caps GM role when the post OV rebuild still hasn't succeeded and Patrick gets non-renewed.
