Victor Marx leads the Colorado Republican gubernatorial primary at 56.5% amid a June 30 vote, driven by his commanding fundraising total exceeding $2.5 million—more than rivals combined—and a late-May poll of likely primary voters showing him at 59% support. As a political newcomer and ministry leader who secured ballot access through the party assembly process, Marx benefits from strong alignment with delegate preferences that favor ideologically conservative candidates. State Sen. Barbara Kirkmeyer trails at 33%, drawing on her legislative record and petition qualification but posting weaker fundraising and polling. State Rep. Scott Bottoms and the remaining field hold single-digit shares, reflecting limited momentum ahead of the final weeks of campaigning.
