I'm wondering if we shouldn't just raise their salaries, put an end to per diem payments, and caps on travel. 
In any event, Tuck's "fair is fair" comment sounds like retribution for doing the right thing. 
Per diem payments should be based on mileage; say 65 miles from their district boundary. This way, Anchorage and most valley legislators are not compensated with a per diem during a special session; or wherever the session is held. Tuck's comment is childish at best. 
We need to save money whenever we can, and legislators from Juneau, living and working in Juneau, don't need per diem to cover costs associated with their service to constituents in Juneau. 
The issue of per diem should be administrative rather than political. It appears Tuck is more interested in a political fight versus doing the right thing.
