A well-funded Republican group trying to stop Donald TrumpDonald John TrumpLondon terror suspect’s children told authorities he complained about Trump: inquiry The Memo: Tide turns on Kavanaugh Trump to nominate retiring lawmaker as head of trade agency MORE is going on the air in Florida with a new ad criticizing the GOP front-runner's use of profanity.

The 30-second spot, supported by a buy the group said cost "hundreds of thousands” of dollars, portrays Trump as a person who uses language that is the opposite of presidential.

In the ad, a screen set up in front of a White House lectern shows Trump saying, “I went to an Ivy League school. I’m very highly educated. I know words. I have the best words.”  

The ad then cuts to various public appearances in which Trump uses profanities including “motherf---er,” “ass,” “pussy,” “damn,” “s--,” and “f---.”

American Future Fund Political Action spokesman Stuart Roy told The Hill that the ads will begin airing Tuesday in the conservative Pensacola and Panama City areas in advance of the March 15 Florida primary.

The action group is a super-PAC affiliated with — but functionally separate from — the nonprofit 501(c)(4) group American Future Fund, which is already blasting Trump with millions of dollars' worth of attack ads, including its own $1.75 million Florida buy. 

The groups' efforts are supported by a frantic last-minute campaign to defeat Trump by the Club for Growth, which on Monday announced a new $2 million ad campaign against Trump in Illinois; Our Principles PAC, run by former senior Mitt Romney adviser Katie Packer; and Conservative Solutions PAC, a pro-Marco RubioMarco Antonio RubioRubio unloads on Turkish chef for 'feasting' Venezuela's Maduro: 'I got pissed' For Poland, a time for justice Judiciary Democrat calls for additional witnesses to testify on Kavanaugh MORE group.

Republican mega-donors such as New York hedge fund magnate Paul Singer and the Ricketts family, which owns the Chicago Cubs baseball team, are major players in the last-ditch GOP effort to stop Trump from becoming the party's nominee.

The anti-Trump groups are hitting the billionaire from a variety of angles: attacking him for being a "fraud" with his controversial Trump University, highlighting his past liberal views on abortion and taxes, and using decorated veterans to try to undermine Trump's tough-guy image.

Of the new Florida ads, Roy told The Hill in an email, “Donald Trump’s repeated public reliance on profanities and vulgarities to express himself is one more piece in an ever-mounting pile of evidence that he does not have the temperament or moral integrity to lead the world’s greatest nation.

"As the ad concludes, Trump is ‘offensive and out-of-control.’ America and the world are watching, and we can — and must — do better if we are to maintain our exceptionalism and global leadership.”
