Mitt Romney Wednesday unveiled a slew of endorsements of prominent conservative candidates running in national and statewide races in three states.
In Colorado, Romney is backing Senate candidate Ken Buck and five other candidates running for state office. Notably, the former presidential candidate did not endorse Republican gubernatorial candidate Dan Maes, who has been dogged by campaign finance violations.
In Washington, Romney threw his support behind Dino Rossi, who emerged from the state's unique non-partisan primary last week with 34 percent of the total vote.
Romney also announced his support for Matt Mead and Cynthia Lummis in Wyoming. On Tuesday, Mead won the GOP's nomination for governor and Rep. Cynthia Lummis easily defeated her virtual unknown opponent to secure the party's nomination for Wyoming's at-large congressional seat.
Romney made his 100th endorsement of the 2010 election cycle on June 28 – moves that have solidified his role as a major contender for the GOP presidential nomination in 2012.
