Anti-Donald Trump Republicans are readying an ad campaign aimed at getting the GOP nominee to quit the presidential race.

The "Free the Delegates" group that failed to oust Trump at the GOP convention will run a 30-second ad on broadcast networks in Florida, Virginia, Ohio, and Michigan, Politico reported. The ad, titled "Keep Your Word," shows Trump wondering aloud why he would continue in the presidential race if he were losing in the polls as some of his poor polling results flash onscreen.

"Resign the nomination," reads text onscreen near the end of the ad. "Let the RNC replace you so we can beat Hillary."

The prospect that Trump would voluntarily resign from power with 72 days remaining until the election is unlikely, and efforts by #NeverTrump Republicans to put up a viable alternative candidate have fizzled thus far.
