The report derides “outreach” as “when the old order makes a decision and then calls the community leaders to inform them.” Compare that with “inclusion,” when “the community is in on the discussion before the decision.” The report explains: In every campaign it studied, “successful Republicans built minority events into their schedules, created advisory groups from leaders in the communities, developed internships for young people,” and generally showed they wanted to be involved in these communities.

Cory Gardner became Colorado’s first Republican senator in a decade by defeating incumbent Democrat Mark Udall, 49% to 46%. What made victory possible was that Mr. Gardner tied Mr. Udall among Hispanics. Yet he was estimated in the January before the election to have only about 6% to 8% of Hispanic support. As a member of the U.S. House, Mr. Gardner had rejected portions of the Senate’s immigration bill.

Rather than hide, he took his case on immigration—as well as his arguments for economic reform, stronger national security and increased energy production—to the Hispanic community. “Colorado Republicans worked Pueblo, a largely Hispanic area they had traditionally ignored,” reads the report. The Republican also deftly pre-empted Mr. Udall’s abortion attacks: He accused the Democrat of running a “one-issue campaign” and then pivoted to other issues that women cared about—like affordable drugs.
