Victor Marx leads the Republican primary for Colorado governor with trader consensus at 62.5 percent, driven by his strong second-place finish at the April state assembly and a May poll showing him at 59 percent after voters reviewed candidate positions. State Representative Scott Bottoms, who secured top-line ballot placement with 45 percent delegate support, trails at 9.2 percent amid lower name recognition outside conservative legislative circles. State Senator Barbara Kirkmeyer, who qualified via petition, sits at 21 percent as the most experienced elected official in the field but has not matched Marx’s recent fundraising and momentum gains ahead of the June 30 primary. The remaining candidates hold single-digit or sub-1 percent shares reflecting limited assembly or polling visibility.
