In today's debate on Meet the Press, Alexi deconstructed Mark Kirk's lie about being a "fiscal hawk."

David Gregory: The question, Mr. Giannoulias, is should tax cuts be paid for?

Alexi Giannoulias: This is why this race is so important. This is a fundamental public policy difference between myself and Congressman Kirk. He says he's a fiscal hawk.

The Congressman has told some real whoppers during this campaign but that may be the be biggest one of all.He voted for every single one of the Bush budgets, which doubled our national debt, he voted to increase his own pay six times. He voted for the bridge to nowhere twice, he voted to raise the debt ceiling four times.

The list goes on and on.

So Congressman, saying you're a fiscal hawk doesn't necessarily make it true, and your voting record proves that it's not true.

The question is – for the congressman – the $700 billion in tax cuts for the wealthiest americans – we don't have $700 billion – so my question for the congressman is which country do you plan on borrowing $700 billion from? The Saudis? China? We can't afford it, and that's one of the problems, quite frankly, with Washington D.C. this over borrowing, this overspending.
