(CNN) – As the Republican race was focused on South Carolina and Nevada Saturday, Rudy Giuliani ended his longstanding observance of the famous "11th Commandment"– attacking his main rivals as he prepares for the make-or-break Florida primary in just 10 days.
He has often referred to the 11th commandment, first coined by Ronald Reagan: “Thou shalt not speak ill of any fellow Republican.”
The former New York City mayor, who has long said he would only strike at other Republicans in defense of his own record, hit Nevada victor Mitt Romney and South Carolina winner John McCain over taxes.
“I’m running against good men, some very fine, all of whom have very good motivation. But there’s a big difference,” said Giuliani at a Florida campaign event Saturday.
“I supported the Bush tax cuts. John McCain voted with the Democrats against the Bush tax cuts - twice. And Mitt Romney did not, clearly, support the Bush tax cuts.”
Giuliani has avoided the race’s early contests, and is counting on a strong showing in Florida’s January 29 primary to revive his flagging campaign. On Sunday, he will begin a two-day bus tour across the state.
The former mayor is currently locked in a four-way battle for first place in the state with Romney, McCain and former Arkansas Gov. Mike Huckabee.
