Regional Breakdown
Key Trends & 2026 Implications
Hispanic Population +30% Since 2010
Colorado's Hispanic community is concentrated in Denver (Adams and Denver Counties) and the San Luis Valley (Alamosa, Conejos). The community is growing faster than the state average. Pueblo County -- historically industrial and Democratic with a large Hispanic population -- is a key swing states.
42% College-Educated: Highest in Region
Colorado has among the highest college education rates in the Mountain West, driven by tech, aerospace, and biotech sector growth. This demographic strongly favors Democrats in the post-2016 alignment. Combined with Denver metro growth, it makes Colorado structurally D for the foreseeable future.
Michael Bennet Senate Re-Election: Safe D
Senator Michael Bennet (D) is up for re-election in 2026. Colorado is no longer a competitive Senate state. The governor races (Jared Polis term-limited) will be a top-tier open seat where Democrats are heavy favorites. Republicans need an extraordinary candidate and environment to compete statewide.
