Land tuna, Tip Oneil put it best when he said "all politics is local", you cant get much more local than a small reservation. Tribal elections are advertised in the local newspapers and tribal politicians take out campaign adds in those same papers. Can you imagine a politician running a campaign with a strategy of curtailing jobs or how about an inner puget sound tribal canidate running on a platform that had the Makah's out at Neah Bay intercepting all the in bound salmon at Cape Flattery in a Ocean Troll fishery or a beach set gillnet fishery. They dont like to air all the squables in public but politics is the same for the indigenous folks of these parts as it is for everyone.
And as for the paid Bio making the decision he probably (certainly) took the job after having it explained to him that the entity he or she was going to work for had a "Harvest Mandate", which will in some cases lead to reduced goals for escapement, but hey its a job and most of the fellows are trying to do the best they can. After all I have yet to run into a bio. that is responsible for any of the damage to the riparian zones and I still see that as the number one reason we are all grousing about not enough fish to go around.
