The problem is that the fiscal conservative core of the program, as it stands, is just not credible. McCain is promising to extend the Bush administration's tax cuts -- and cut some more. He is also promising to reduce and then eliminate the budget deficit. To do both of those things, McCain would need to make correspondingly savage cuts in spending, and he has not come close to saying how.
We need straight talk from McCain: on how we can sustain (and pay for) an indefinite Iraq occupation and how we can restore fiscal sanity without some increase in taxes.
