Now that MSNBC has said goodbye to its top draw, Keith Olbermann, the news network is looking to find a new marquee star for its growing brand, and sources tell me their ultimate wish list is topped by none other than ’30 Rock’ star Alec Baldwin.

“He’s already part of the NBC family, has a huge fan base and is very respected for his long term passions for politics,” a network source tells me, adding that Alec is very high, perhaps even No. 1, on the wish lists of MSNBC bigwigs…

A friend of Alec’s tells me that if he opts out of politics (and acting, of course), a career as a cable news opinion host would suit him perfectly.
