Larry Kudlow on his program last night:

Tonight I want to talk to you for a quick moment about me. Several weeks ago, I was approached by the Republican Party to consider a run for the US 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.

However, this story seems to have a life of its own. It started as a solitary blog post and then spread like wildfire. 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.

So this evening, I'm letting the world know that I am not running for the US Senate. 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. My great hope is I'll be around this network, doing my thing, for many years to come. So I appreciate your interest and support. The case is closed.
