I think later in the debate, McMumble stated that he'd institute "across the board" cuts to pay for the reduced class size initiative. Why didn't anyone do the stinking math and point out that every single program would have to be slashed 25% to get the $15 billion?
And why doesn't Jeb do a better job of pointing this out in his commercials - as well as the other points made by this article? I'll never understand why Bush family campaign commercials consistently fail to make their most powerful arguments.
