Mediaite reports that Colbert is cratering at CBS. While both Jimmy Fallon and Jimmy Kimmel work really hard to be bipartisan in their comedy, Colbert has stayed left. Consequently, Republicans are turning him out in massive numbers.
Personally, I don’t know that he fits well where he is. His interviews tend to be a bit more serious with more serious people. But at that time of night people are tuning out of politics as a hard topic and just want to laugh.
And Republicans don’t want to watch a guy who can’t bother to be at least equal opportunity in his jokes.
