In my post yesterday on Rudy Giuliani's CNBC interview with Larry Kudlow I suggested that there was "a real opportunity on the Republican side for a candidate to fill the Steve Forbes-kind of role in the GOP field with an unapologetic embrace of low-tax, pro-growth, supply-side policies."

Today the Giuliani campaign announced:

New York City - The Rudy Giuliani Presidential Exploratory Committee today announced that Steve Forbes, President and Chief Executive Officer of Forbes and Editor-in-Chief of Forbes magazine, has endorsed Rudy Giuliani for President of the United States. Mr. Forbes will serve as a National Campaign Co-Chair and Senior Policy Advisor.

"I am honored to support Rudy Giuliani for President," Steve Forbes said. "As Mayor of New York City, Rudy Giuliani showed how exercising fiscal discipline - including tax cuts - lowers deficits, spurs economic growth, and increases revenue. It is time the rest of the country benefit from a true fiscal conservative leader who gets real results."

"Steve and I share an economic vision that embraces supply-side economics, tax relief, and spending restraint," said Mayor Giuliani. "I look forward to working with Steve and am proud to have him as a member of our team."

Rudy leads by 15.8% in the latest RCP Average (Giuliani 33.4, McCain 17.6).
