Donald Trump succeeded in branding his chief rival in the Republican primaries a liar, and Democrats are taking a page out of his playbook by using Trump’s own legacy of misstatements and falsehoods to try to define the presumptive GOP presidential nominee as a pathological liar.

Correct the Record, a super PAC supporting Hillary Clinton, is launching a “Trump Lies” campaign on Thursday that catalogs the business mogul’s lies and inaccuracies, dating from the start of his real estate career in the 1970s to his current campaign for president.

Thursday’s launch includes an interactive website, TrumpLies.com, which contains a searchable database of Trump’s misstatements, as well as a 40-minute video highlighting his struggles with the truth since announcing his candidacy a year ago.

The video, set to the entirety of Mozart’s Symphony No. 41, includes every Trump statement that has been thoroughly debunked by The Washington Post’s Fact Checker. The group will update its lies database as the campaign unfolds and plans to continue adding multimedia features and other new material, such as weekly roundups of falsehoods, between now and Election Day.

“Compulsive lying runs through every facet of his life and his candidacy,” said David Brock, who runs Correct the Record and other outside groups aligned with Clinton.

The strategy, Brock said, is to use Trump’s frequent misstatements as a character issue and convince general election voters that he lacks the temperament, judgment and character to serve as president.

“His appeal is that he is supposedly a straight shooter, and you have to ask the question, ‘How can someone who basically lies every five minutes be a straight shooter?’ ” Brock said. “We want to try to undercut that reputation by demonstrating the depth, breadth, substance and consequence of his lies.”

The effort inserts Brock’s group into an ugly war of accusations with Trump. After Clinton’s foreign policy speech Friday excoriating Trump’s temperament and fitness for office, Trump declared that he would reassign to Clinton the “Lyin’ ” moniker he previously had relished bestowing on Sen. Ted Cruz (Texas).

“I want to save that now for Hillary – lyin’, lyin’ Hillary,” Trump said at a rally in San Jose. “She is a liar.”

The challenge for Clinton and her allies will be to demonstrate that Trump is a liar of a higher magnitude, Brock said.

“Voters think all politicians lie, but we have to demonstrate that Trump’s lying is different, not just in degree but in kind,” he said. “The volume, the magnitude and the sheer brazenness of it is without precedent – and that’s dangerous in a leader.”

Although the super PAC’s objective is serious, it is taking a tongue-in-cheek approach. Previewing the Trump Lies project, officials said the first misstatement they have documented of Trump’s campaign came in the first nine words he uttered.

“Wow. Whoa. That is some group of people. Thousands,” Trump said after coming down the escalator at Trump Tower last June to formally announce his candidacy.

According to news reports, however, about 300 people were in attendance in the building’s atrium for the big announcement.
