Baldwin, the 55-year-old former costar of NBC's sitcom "30 Rock," would bring his famously liberal point of view to a show that would air at 10 p.m. Fridays, according to the site Mediaite, which broke the story.
The cable news wars are heating up again. News of Baldwin's possible show broke the same day that reports indicated Fox News anchor Megyn Kelly would get the 9 p.m. slot currently occupied by Sean Hannity.
A talent representative said a deal is believed to already have been signed, but an MSNBC spokeswoman declined to confirm that or comment on the Mediaite report.
Baldwin would be a choice almost guaranteed to hearten liberals as much as it would irk conservatives. The actor has been an outspoken left-wing advocate for years, making him a favorite of Democratic viewers.
Earlier this year, however, he was attacked for calling a British reporter "a toxic little queen." Many observers, including CNN's openly gay Anderson Cooper, said that a conservative who said the same thing would have been viewed as homophobic, but that Baldwin got a free pass because of his politics.
What's certain is that Baldwin knows how to make news, intentionally or not. In 2007, he made international headlines when he left a voice message berating his then-11-year-old daughter as a "rude, thoughtless little pig." He later apologized.
What do you think of Baldwin possibly getting an MSNBC show?
