TNT scores with ‘Mates’

Earns highest made-for-cable movie ratings this year

NEW YORK — TNT slotted “Running Mates,” its firstrun movie about the behind-the-scenes maneuvering at a political convention in Los Angeles, on the Sunday before the real-life Democratic convention in L.A., and the move paid off big time.

From 8 p.m. to 10 p.m. on Aug. 13, “Running Mates,” starring Tom Selleck as a presidential nominee, scored a strapping 5.6 rating in cable homes, which propelled it into a three-way tie for highest-rated made-for-cable movie of the year with USA network’s “The Mary Kay Letourneau Story” and TNT’s first part of the four-hour “Nuremberg” movie.

The success of “Running Mates” elevated TNT into first place among all basic-cable networks for the week, helped also by the Aug. 12 run of “The American President,” with Michael Douglas, which harvested a 3.4 rating in cable homes.
