Oh snap! Hillary Clinton hits Donald Trump with a string of 'face swaps.'

Hillary Clinton put a new face — actually, several — on the political attack ad in a Snapchat campaign targeting Republican presidential front-runner Donald Trump.

The Democratic presidential candidate used Snapchat’s new “face swap” feature to superimpose the images of prominent past Republican presidents on Trump’s visage to lampoon the billionaire real estate mogul’s claims that he would begin acting “presidential.”

One of the ads puts Abraham Lincoln’s angular face on Trump while calling out the candidate for refusing to disavow the endorsement of white-supremacist David Duke, former grand wizard of the Ku Klux Klan. Another puts the image of Dwight D. Eisenhower, a World War II hero, on Trump as it notes his disparagement of Arizona senator and former POW John McCain.

The series employs other notables — Ronald Reagan, George H.W. Bush and George W. Bush — while referencing Trump’s calls for a ban on Muslims entering the U.S., his mocking of a New York Times reporter with a disability and his statement about punishing women who have abortions (should the procedure be declared illegal).

The effect is … disturbing, leaving the viewer with the impression of Trump as, well, Frankencandidate.

Snapchat, with more than 100 million active daily users, has emerged as the 2016 election campaign’s platform of choice for novel political ads. Candidates look to the popular app as a way to reach voters under the age of 34, nearly half of whom are on Snapchat on any given day.

A Super PAC supporting Florida Sen. Marco Rubio used Snapchat’s geofilters in Virginia to tag Trump as a “con artist” and emphasize his failed Trump University, which is the subject of a fraud suit. Texas Sen. Ted Cruz sponsored a Snapchat filter to label Trump as “Ducking Donald” when his opponent refused to participate in a Republican presidential candidates debate.
