Giuliani supporters tout tax-cut plan in new ad

Rudy Giuliani calls on well-known conservatives to vouch for his tax-cutting plans in a new TV ad in his must-win state of Florida.

As martial, upbeat music plays, the ad lists glowing quotations from Grover Norquist, George Will, Steve Forbes, and a leader of the Club for Growth, a Washington anti-tax group that has ripped Mike Huckabee, one of Giuliani's presidential rivals, in TV spots.

The ad also cites Americans for Tax Reform's praise for Giuliani's plan as the biggest tax cut in history.

And it even quotes another Republican rival, Mitt Romney, saying “Mayor Giuliani has a great record of cutting taxes.” The ad, however, does not cite a date or source for that quotation. In a memo sent to reporters, the campaign cited a CNBC report after a debate last October.

During the campaign, Romney has been far more critical of Giuliani's fiscal record as New York's mayor.
