They can't raid the principle because this is not general funds it's permanent funds.  

Please do some research before commenting so you don't make yourself sound completely ignorant on the subject. 

The reason it is called a permanent fund is because the principle cannot be touched which is why certain political movements have shifted money into the principle where it can no longer be used as a revenue for spending.  

The saying that we will be without a AK permanent fund in 4yrs is a lie; it's likelier that we would be without a dividend check for a few years because the earnings would be used up on services.
