Your sales ta suggestions are "regressive".  
That`s why they were considered but the people don`t support sales taxes only.. and that would be on top of communities that already have a sales tax. Another on top of that to them would be an unfair burden of another layer of sales tax.  And if you exempt them your defeating the whole reason for trying to raise a demonstrably fairer broad-based progressive state income tax like the majority of other states in "The Union" use..  
An progressive income /SCHOOL TAX would be far more effective at budget relief than any combination of sales taxes.  The slope workers bringing their payrolls back to Texas don`t buy much in Alaska to pay sales taxes on. If they paid a state income tax it would be $85 million, every year, that could be applied to school and education costs..
