(CNN) - They're at it again.
Rand Paul was asked in a recent interview to name one word when he thinks of fellow Republican Chris Christie.

"Bridges?" he said with a knowing grin during a sit-down with KET's Bill Goodman.
The Kentucky senator’s dig marks the latest round in the back-and-forth between the two potential presidential contenders - a feud started last year in a war of words about surveillance and government spending.
Christie’s administration has been rocked by scandal over suggestions top appointees orchestrated the closure of access lanes to the George Washington Bridge last year – causing big traffic tie ups - as political payback for a local mayor who did not back the governor’s reelection.
A state legislative committee is spearheading an investigation, while federal prosecutors are also reviewing the matter.
Although there is no evidence that Christie was involved, the scrutiny and the resulting controversy continues to dog him. It has also raised questions about his leadership and forceful governing style that has been popular with New Jersey voters.
Paul was also asked to briefly describe other potential White House rivals, including Texas Gov. Rick Perry, another conservative with whom Paul has recently sparred.
"It's hard to put it in one word," Paul said. "I like the fact that he has been for more power for states and for less government in his state. We have some disagreements on some other things.
Hillary Clinton? "Yesterday's news," he said.
Barack Obama? "Affable but often ineffectual."
Marco Rubio? "Thoughtful and part of the answer to making our party bigger - a good, new face for our party."
Paul on bridge scandal: People shouldn't feel bullied by govt.
Folks with working brains on Rand Paul in one word: Plagiarist.
Folks with working brains on Rand Paul in 4 words: Cut Aid to Israel.
Folks with working brains on Rand Paul in one word: Fake.
Little Ayn Rand Paul and big fat bully boy. The best the GOP has to offer!
Mr. Paul's role heading towards the GOP's convention in Cleveland is now clear....comic relief.
-Are these the guys vying for WH bid? These guys are not even qualified to be cooks in WH kitchen. GOP is gone to dogs.
Bridges? What bridges? I thought Republicans didn't care about any stinking bridges.
Yum yum, it him up!
Paul, the big tough guy who ran away from a young Latina lady trying to speak to him.
@rs: "Mr. Paul's role heading towards the GOP's convention in Cleveland is now clear....comic relief."
Maybe he'll recite another mangled limerick like he did at the recent repub “Fancy Farm” picnic and rally.
Such a literary guy, dontcha know...
Sen Paul just couldn't help himself...Gov Christie is a big and easy target.
Throwing the big guy under the bus already? Weren't they holding hands just a week or so ago? Danced around the Cuban water boy.
As far as Obama and Hillary, what's he going to say, they can beat me without really trying?
Two words when I think of paulie girl from now on, hamburger runner.
And the repubs wonder whats wrong with their party !!!
Rand Paul is the new owner of the phrase, "I was for it before I was against it."
He is better than the alternatives
CNN – Certainly Not News! More like Hollywood Insider or Enquirer.
Where are the aliens? Oh, I forgot they are all in DC.
Perry doesn't like the American government in his state? Hah – that's rich! Perry is the poster child for governors who are always asking Obama for help.
the one word for Rand Paul: rug (and bad one at that).
One word for Rick Perry: "Oops"
He's obviously hedging his bets on Perry. I could certainly think of several one-word descriptions but decline stating them here for security reasons!
Obama in one word, SCANDAL.
"Although there is no evidence that Christie was involved..."
This is an absurdly irresponsible statement for a news agency to make. No evidence? Do you even know what the word "evidence" means? There is a TON of evidence that "Christie was involved." God, you people have gone downhill in terms of journalistic standards. It's pathetic.
Interesting that you used Christie as your headline and not Obama : Ineffectual or Clinton : Yesterday's news. I did not know that Christie was a bigger headline grabber than the other two? Interesting choice.
Rand Paul in one word: flipflop
Rand Paul in one word: plagiarism
