It had been one of the many points of contention against CNBC by the left-wing attack machine - that "The Kudlow Report" host Larry Kudlow was using his show as a platform to make a run at the U.S. Senate in 2010 against Democratic Sen. Chris Dodd.

Well, they're going to have to find another way to try to marginalize Kudlow, as they have with other CNBC personalities. Kudlow announced on his March 24 broadcast that he would not seek a seat in the U.S. Senate in 2010.

The CNBC host explained he was approached by the Republican Party to be a candidate, but said he never considered it "a serious proposition."

"Alright folks, tonight - I want to talk to you for a quick moment about me," Kudlow said. "Several weeks ago, I was approached by the Republican Party to consider a run for the U.S. Senate in the great state of Connecticut. It was a flattering conversation and one that I thought about, but to me it was never really a serious proposition."

The story gained steam after one prominent blog picked up the report, however Kudlow never directly responded to the report until March 24.

"However, the story seems to have a life of its own now," Kudlow continued. "It started as a solitary blog post then spread like wildfire. And now, CNBC, my network, is getting questions from a number of high-profile reporters wanting to know what I'm going to do. I'm glad they care."

Kudlow explained he had just signed a long-term deal with the network and didn't plan on going anyway.

"So this evening, I'm letting the world know that I am not running for the U.S. Senate," Kudlow said. "And here's why - in my heart, I know that I belong right here at CNBC. This is my love. I just signed a new long-term deal here and I can't think of anything else I would rather do. I've invested and worked very hard at this job and I am so blessed to have it."

Kudlow critics will have to find another reason to attack the CNBC on-air personality. Perhaps they can consult CNN's Lou Dobbs for pointers.

"My great hope is I'll be around this network doing my thing for many years to come," Kudlow said. "So I appreciate your forbearance. Now, the case is closed on that."
