Pat Buchanan and MSNBC have officially parted ways. The veteran conservative commentator had not appeared on the network since October when he began promoting his book Suicide of a Superpower: Will America Survive to 2025?. An MSNBC spokesman said, “After 10 years, we’ve parted ways … We wish him well.” Buchanan joined MSNBC in 2002 after two decades as a rotating host of CNN’s Crossfire. In the years since then MSNBC has tilted much further to the left. In January MSNBC president Phil Griffin said the ideas expressed in Buchanan’s book put forth “aren’t really appropriate for national dialogue, much less the dialogue on MSNBC.” Buchanan wrote today in an essay on the website for The American Conservative magazine, which he co-founded: “In the 10 years I have been at MSNBC, the network has taken heat for what I have written, and faithfully honored our contract. Yet my four months’ absence from MSNBC and now my departure represent an undeniable victory for the blacklisters.”
