While the Republican primary for Senate is shaping up closer than expected in Colorado, the Democratic one is going in the other direction. Michael Bennet has now opened up a 15 point lead, 46-31, over Andrew Romanoff as he attempts to win nomination for a full term. That's a 9 point increase in his advantage since leading 40-34 in a March poll of the race.
The key thing for Bennet is that he's winning similar levels of support from liberals, moderates, and conservatives. He has an 18 point lead with moderates, a 15 point one with conservatives, and it stands at 11 points with liberals. Romanoff clearly isn't getting much traction from the left and Bennet's across the board advantage ideologically bodes well for his ability to unite the party around him for the fall if he does indeed win the nomination.
The one group Bennet continues to be weaker with is Hispanics, who are splitting their support evenly between Romanoff and the incumbent right now. Bennet is still making progress on that front though- he trailed by 11 with Hispanics in March.
This race is not over by any means but the momentum is clearly in Bennet's direction.
