The USA network drama - which stars Sigourney Weaver - launched with 2.6m viewers on July 15, but ratings have dropped in recent weeks.
However, NBC Universal's Bonnie Hammer told TVLine that a decline in viewership may not spell the end for the political series.
"We want to see what the response is [and] what kind of interesting buzz it brings to USA as a whole," she said.
"It's never just, 'Do you hit a certain rating?' - it's really about the whole, what it adds to USA as a brand."
Political Animals creator Greg Berlanti added that all of the show's major stars are "contracted for multiple seasons".
"We have a whole life of the characters [planned out] - some of which is set up in these [first] six [episodes], and a lot of which we pay off in these six," he explained.
Political Animals continues on Sundays at 10/9c on USA.
