In 2016, the group is taking every opportunity to do the same thing with Donald J. Trump. It is maintaining an archive of digital video footage, with 6,500 clips of Mr. Trump speaking or being mentioned, going back to the 1980s, and 17,000 hours of footage over all. It has also compiled more than 5,000 pages of research on the presumptive Republican nominee and has 25 trackers monitoring him.
American Bridge is playing a more significant role in 2016 than it did in 2012, when the Obama campaign was leery of the group, which was founded by a close ally of Hillary Clinton’s. This cycle, Democrats have relied on it openly for research.
There are special systems that allow it to search by specific strings of words to identify issue targets. It is trying to expedite their ability to quickly frame a case against Mr. Trump. And it is monitoring roughly 600 candidates up and down the ballot, in addition to Mr. Trump.
Asked about the plagiarism, which was discovered by the Democratic “super PAC” American Bridge, the editor of the Trump Institute publication, Susan G. Parker, denied responsibility and suggested that a lawyer for the Milins, who provided her with background material for the book, might have been to blame.
