Looked at similar questions during my search. Oregon has the most to lose if the F15 goes away due to K-falls being the training base. So the state as a whole will maneuver to keep the F15, but if they get something else that sends federal pork to Oregon, the state powers won't care if it is a blimp or fighter. That said, the F15C/D will have to go away at some point. Whether it is replaced by the F15X, F35, a new F22 line, a brand new clean sheet fighter, or some unmanned aircraft is totally subject to political maneuvering that is outside the desires of any unit as matmacwc said. The remaining F15 locations that hire for UPT would probably have to be replaced by some sort of fighter if the F15 goes away - but the safest are those that have no other fighters nearby like Fresno and Portland.
I would also argue that the K-Falls location would be silly for the AF to give up due to the costs of the area being fairly low, high flyable days a year, balmy winters, and no hurricanes/tornados. However logic like that is not used in deciding base realignment/closure. Part of your search might also include where you can get your day job when the guard flying dries up, who you want to spend considerable amounts of time with (each unit has a different culture), and who is willing to say yes to you too. If air to air is the mission you want, visit the F15 units that are hiring and decide. If you want to mix it up with some air to ground then check out the -16 and -35 units as well. If you want to be in a fighter at all costs and don't have things in your file that distinguish you head and shoulders over your peers, then find whoever will say yes to you and run with it. There is definitely tough competition out there for the boards. Years down the road, after you pay your dues, you can apply to a rated board elsewhere and even in a different airframe if that's what you want at that point.
