What Are We to Make of Tucker Carlson’s “180?”

Tucker Carlson has made what is perhaps the most dramatic flipflop on U.S. political history, from a Fox News host moron to a liberal intellectual.  I had to smile when I came across this video, where he cautions an Israeli leader not to describe Iran as a “terrorist regime,” when Israel itself is murdering thousands of children in Gaza.

My only problem with him at this point is that I have to think he’s completely insincere.  Can someone go from a Trump supporter to Bernie Sanders on the basis of some awakening late in life?  Isn’t it more likely that he sees better financial opportunity with his current position?
