It is the longest of long games.

Yet, a group of Republicans who are dismayed by Trump and alarmed by his slipping poll numbers will be running ads in key states across the country, calling for Trump to step aside, according to a new report from Politico.

The ad, which was sponsored by the group “Free the Delegates” will run in suburbs in Florida, Virginia, Ohio and Michigan, according to Politico. Free the Delegates had tried to stop Trump at the Republican convention, but had fallen short. The ad is titled “Keep Your Promise,” which is a throwback to a comment Trump made early in the campaign that he’d bow out of the presidential race if he was far behind in national polls.

“Resign the nomination. Let the RNC replace you so we can beat Hillary,” the ad read at the end.

The ad buy was fairly limited and was only five figures, Politico reported. In an interview with Politico, Regina Thomson, who runs Free the Delegates, told Politico that eventually the group hoped to get enough money to run the ad on Fox News.
