(CNN) - Rudy Giuliani hailed former Florida House Speaker Marco Rubio Monday as the "one candidate that [Florida Republicans] can trust" to uphold conservative values in Washington.
"This is an easy choice in this race," the former New York City mayor said at a press conference in Miami before a gathering of Rubio supporters. "This is an easy choice for a Republican because he is the one candidate that we can trust to represent Republican principles in Washington and remain a Republican if he goes to Washington."
Rubio will face Florida Gov. Charlie Crist in the GOP senatorial primary in late August.
Giuliani's endorsement is among Rubio's most high profile to date, and is being seen as political payback to Crist who refused to endorse the former New York City mayor during his presidential bid two years ago.
Crist instead lent his last-minute support to Arizona Republican John McCain, who ultimately won that state's pivotal presidential primary and effectively ended Giuliani's hopes of becoming the GOP's presidential nominee.
A Mason-Dixon poll late last month showed Rubio leading Crist among Republican voters by 11 points, 48-37 percent. Fifteen percent in that survey remained undecided.
But it was almost as if Giuliani was back on the presidential campaign trail himself Monday, using much of his 10-minute endorsement speech to criticize President Obama's policies - specifically his approach to the war on terrorism.
"Let's have an America that stands up to terrorism, not an America that has ambiguity and confusion," Giuliani said. "Do we want to see people like Khalid Sheikh Mohammed tried in New York? Or Miami? Shouldn't he be tried in a military tribunal?"
"The president can't make up his mind," he continued. "Do you understand what kind of lack of leadership that shows to the rest of the world? I tried over 4,000 criminals. The easiest decision I had was where to try them."
Look like Rudy is still whinning about something that happen two years ago when Gov. Crist who refused to endorse the former New York City mayor during his presidential bid .
Giuiliani should keep his nose out of other states' business.
Another has been..He needs to look into his own back yard before pointing fingers at anyone..He's a Fool......
this two time failure as a husband and failure as a Presidential Candidate would know about 'lack of leadership", wouldn't he? What an embarrassment to the Republican Party and to humanity in general
Like Rudy Giuliani really has any creditability...not to mention he was beat by John McCain. Therefore, I can really see Gov. Crist winning now!
who cares what Rudy says and what makes him a shotcaller, his opinion is just that, and everybody has one
just like giuliani's presidental nomintation bid... i and most of florida say a big WHATEVER!. .
Mr. 9/11. Please, go A W A Y!
Rudy Giuliani is a bonehead. Who cares what you did as Mayor. It's a whole different league you dork. Go back to pony baseball, you're not ready for the majors.
I guess exploiting 9/11 doesn't work for ya anymore. LOSER
Didn't Guliani endorse his former police commissioner for Secretary of Home Land Security; who turned out to be a criminal and serve time in prison for stealing and other unethical behavior as a public official? So much for his endorsement. I wonder why Rubio would even want to be endorsed by someone of Guliani's questionable character – to say the least? Birds of a feather do what???? Flock together.
To Guiliani and all the other Obama bashers: President Obama won the election and he is President of this US of A. Live with it.
And Guiliani, not every one agrees with your conservative principles. They have been tried and have been found wanton.
This guy is unreal . First he changes from Democrat to Republican. Then he runs for the GOP Presidential nomination( he is NOT ENDORSED BY Crist) and his whole stradegy was to win big in Florida over McCain. Now he endorses Rubio over Crist. Not much of a track record...I sure wouldn't want his endorsement. Sounds like the kiss of death !!!
Preston kathy all rudy has past 9ii he does not even have that
Shutup Rudy. No one takes you seriously or cares about you. You have so many skeletons in your closet, I wish you would try to run for something so we could all sit back and watch your crap implode a la Bernie Kerik.
Who cares what a mayor thinks about the President... if he was the mayor of LA or Nuttbush Tenn? Stick to what you know best Rudy... exploiting peoples grief and fear to win an election.
With all his attempts to destroy the President, Guiliani is more of an enemy today than he ever was a patriot after 9/11. The GOP spoke in the last primary and labeled him a loser. Please dear God, give him a big enough foot to shove down his throat and shup him up.
Guliani = Conservative = Adulterer = Cheater
Didn't you only have only place the try them? Giuliani, what are you taking us for? It's easy to lead when no one will follow
Ok, so which of Giuliani's republican principles is he hoping Rubio represents in Washington: adultry or the employment of criminals? I have nothing against Rubio, but this is pretty rich coming from Giuliani.
Can you say MOOOOOOROOOOONNNN! Shut up and go to alaska with the other idiot!
Who cares what this has been says or thinks. If you have something to say, then I hope that you decide to run for office. Of course you know that there is no chance you will get elected.
One clueless out-for-himself idiot endorses another, proving yet again how out of touch the GOP is with Main St. America.
One horses behind recommends another horses behind. Rudy's recommendation doesn't mean squat to me. Rudy is a man who can not be trusted and should go hide out with George Bush, Jr.
Why do we care what Rudy thinks? Anyone?
Rudy has a little bit of crazy in him. I like him, but he can't come over for dinner. I don't even know what wife he'll show up with.
