As if they wouldn't. When wouldn't they support a Dem Pres? That's like saying Ohio State Buckeye fans rooted for the Buckeyes yesterday.
FWIW, note the wording. "Late Night reflects..." Not Late Night Comedians. That's about the fifth time now I've seen them referred to that way, including by the morning network news shows.
It's as if even the press can't bring itself to continue the charade. They're not comedians. They're leftwing thralls, hacks and activists who exist to bow before the Left and attack its enemies. Followed by the obligatory flashing signs [LAUGH]/[APPLAUSE]
Another example of the NYT being honest:
When you've become such partisan hacks that the propaganda press can't bring itself to continue the act, it's time to come out of the closet.
