Hillary Clinton helped Jimmy Kimmel beat Stephen Colbert for the first time in total viewers and the demo.

During the week of November 2, ABC’s Jimmy Kimmel Live beat CBS’ The Late Show With Stephen Colbert in both metrics – a first since Colbert took over as host of Late Show. In total viewers, Kimmel led Colbert by 5% (2.626 million vs. 2.492 million); Kimmel also led by 5% in the demo (765,000 vs. 728,000).

Kimmel’s guest that Thursday: Democratic frontrunner Hillary Clinton, making her first visit to Kimmel’s show as an official candidate. She delivered Kimmel’s biggest overall audience on any night – 3.116 million viewers – since an NBA finals-led telecast in June, 6 months back. Excluding the NBA finals-led broadcasts, Thursday’s telecast snagged Kimmel’s biggest crowd in more than eight months.

Also that week, NBC’s Tonight Show Starring Jimmy Fallon inched up his margin over Late Show to a biggest-yet 60% in demo rating (0.91 vs 0.57).  It’s the third time in a row Fallon has delivered a best-yet margin versus a week of Colbert originals. NBC’s Late Night With Seth Meyers pulled within 0.05 of Colbert (0.52 vs. 0.57) and within 0.08 of Kimmel (0.52 vs. 0.60), despite airing an hour later.

It’s the third week in a row (excluding a week of Colbert encores) Fallon has delivered biggest-yet margins versus The Late Show. Previous week, Fallon dominated Colbert by 58%.

For the week of November 2:

Fallon logged a 0.91/5 in the demo and 3.37M viewers. Kimmel clocked a 0.6/3 in the demo and 2.63M viewers. Colbert averaged a 0.57/3 demo rating and 2.49M viewers.
