This just broke on Fox News.
I will update when I have more.
Update: The AP is reporting:
Former New York City mayor Rudy Giuliani, a moderate Republican best known for his stewardship of the city after the Sept. 11 terrorist attacks, has taken the first step in a 2008 presidential bid, GOP officials said Monday.
The former mayor filed papers to create the Rudy Giuliani Presidential Exploratory Committee, Inc., creating a panel that would allow him to raise money for a White House run and travel the country.
The four-page filing, obtained by The Associated Press, lists the purpose of the non-profit corporation "to conduct federal 'testing the waters' activity under the Federal Election Campaign Act for Rudy Giuliani."
Giuliani was widely praised for leading the city during and after the terror attacks of Sept. 11, 2001. He has said for months that he would wait until the end of the 2006 elections to decide whether to embark on a White House bid.
I like Rudy Giuliani. I like Mitt Romney as well, if not more, but I'm thrilled that Rudy is seriously interested in running. He'll make a fantastic candidate.
Added: Commenter Steven notes that Rudy is anti-gun, pro-choice, and pro-gay marriage. These are the issues that will be the sticking point in the primary should he choose to go forward with running for president.
Update: Remember the GOP Straw Poll? Rudy is just behind Newt Gingrich 26% to 24.5%.
