On his blog post, Pat Buchanan lays out a long list of reasons for his departure from MSNBC — including protest from Color of Change, the Anti-Defamation League, the Human Rights Campaign and Media Matters.

Buchanan, 73, was suspended from the cable channel earlier this year, what he says was because of his book “Suicide of a Superpower: Will America Survive to 2025?”

But what about demographics? Cable channels median viewership skews well beyond the age of the audience most coveted by advertisers. Like the rest of TV, the pressure is to go young.We’ll see where Buchanan lands next.

In the meantime, Joe Scarborough and Mika Brzezinski, stars of MSNBC’s “Morning Joe,” issued a statement criticizing the decision.

“Everyone at Morning Joe considers Pat Buchanan to be a friend and a member of the family. Even though we strongly disagree with the contents of Pat’s latest book, Mika and I believe those differences should have been debated in public. An open dialogue with Morning Joe regulars like Al Sharpton and Harold Ford, Jr. could have developed into an important debate on the future of race relations in America.

“Because we believe that sunlight is the best disinfectant, Mika and I strongly disagree with this outcome. We understand that the parting was amicable. Still, we will miss Pat.”
