The Democratic National Committee amassed a mountain of information to defend Hillary Clinton as the party’s presidential nominee — long before the first primary election, according to internal documents.

A hacker known as “Guccifer 2.0” released another round of documents Tuesday allegedly stolen from the DNC’s computer files and they show that the supposedly neutral committee devoted enormous resources to groom Clinton ahead of all other Democratic contenders for the White House.

An April 23, 2015, memo from Brian Fallon, Clinton’s press secretary, discussed how to discredit the “Clinton Cash” book by Peter Schweizer. which revealed how the Clintons amassed a fortune off their government service.

“The bottom line remains that the book fails to produce a shred of evidence supporting the theory that Hillary Clinton ever took action as secretary of state for the purposes of supporting the interests of donors to the Clinton Foundation,” the memo said.

A second memo dated three days later from Fallon expressed gratitude for all the support in undercutting the author.

“Today, we believe we turned a corner as the author himself, Peter Schweizer, conceded multiple times on national TV that his conspiracy theories lack any evidence and that he omitted key facts from his own reporting,” the memo addressed to “friends and allies” said.

Other documents show Democratic operatives building a heavy armor of research to shield Clinton.

A file titled “HRC Defense — Emails” includes critical quotes from GOP presidential candidates about Clinton’s use of a private e-mail server and how Clinton or her aides fought back in various publications in March 2015.

The document “Clinton Foundation Vulnerabilities Master Doc FINAL” detailed attacks on the foundation from 2007 through 2015 — with some recommended responses.

Bill Clinton’s sex life even turned up in the files with records tracking when Republicans made references to it.

The files also showed that Democratic operatives were preparing for Joe Biden and Elizabeth Warren to enter the race.

A file called the “2016 Democrats Position Cheat Sheet” includes detailed positions and voting records for seven Democrats: Clinton, Bernie Sanders, Martin O’Malley, Lincoln Chafee, Jim Webb — all of whom were candidates — as well as Biden and Warren.

Another of the 250 files dumped Tuesday spelled out the strict requirements for hiring Clinton as a speaker.

Aside from the standard $225,000 fee and expenses, one document stated that Clinton would only fly in a “Gulfstream 450 or larger” private chartered jet.

The Clinton campaign did not respond to a request for comment.
