A NewsBusters study reviewed the five daily late-night comedy shows since their return from the writers' strike nine months ago to confirm or debunk whether a political bias exists.  

The watchdog recorded each political guest who has appeared on the following programs from October 2, 2023, to June 27, 2024: ABC’s Jimmy Kimmel Live!, NBC’s Late Night with Seth Meyers and The Tonight Show Starring Jimmy Fallon, CBS’s The Late Show with Stephen Colbert and Comedy Central’s The Daily Show.

The results: 94% of guests were liberal. Just eight conservative guests have appeared on any of the five shows since October, compared to 137 liberal guests.

MRC analysts also divided the guests into two categories: partisan officials and then journalists and celebrities. In terms of partisan officials, 34 Democrats to five Republicans.

"Colbert led with the greatest cumulative discrepancy at 14-1. Kimmel’s count was 7-0, Meyer’s was 3-0, and Fallon’s was 1-0. The Daily Show came in at 9-4," details the report.
