We have cut enough without looking at the big picture. Your partisan "anti-government" blinders refuse to use the other tools most educated people agree we need to include in the fiscal fixes. 
To dismiss them out of hand as the OILY Senate leadership has done, without an earnest, honest, and open vetting in the legislature, (we had a state income tax before 1980 and we survived..not a small fact)  when every single other state in the Union employs either a sales or income tax to help fund government and societal operations, is ludicrous.  Another two cents..
