The effort, which began in late spring, covers Vice President Mike Pence, Ohio Gov. John Kasich, United Nations Ambassador Nikki Haley and Nebraska Sen. Ben Sasse, among others.

“With Trump’s tumultuous presidency in complete chaos, we are prepared for all scenarios,” said DNC research director Lauren Dillon, confirming the campaign to POLITICO.

In the case of Republicans like Pence and Kasich, the team of over two dozen DNC researchers is mostly updating the existing research books they deployed in 2016, according to Democrats familiar with the arrangement. For the others, the operatives are combing through voting and governing records, compiling financial files, searching for conflicts of interest, and saving clips on their relationships with Trump.
