From M E M's political news source of choice, an entry I find hard to argue with...

NBC's Williams heard McCain's attacks on Obama's economic plan, but didn't ask how McCain would pay for his tax cuts

...that Obama's new spending ( 1.4 trillion) is roughly equal to McCain's lost revenue through tax cuts (1.5 trillion).

Is it possible that McCain's tax cuts will result in more taxable revenue? That's been my observation in the past, that tax cuts result in increased business and jobs, which translate to more taxable income, that more than compensates the tax cuts.
