Since the last Policy Brief election update, several more states advanced in the primary season process, including Colorado and Texas. In Colorado, Democratic primary voters rewarded several anti-establishment candidates while still preserving some incumbent strength. Attorney General Phil Weiser’s won over U.S. Sen. Michael Bennet in the Democratic primary for Colorado governor. Bennet’s loss means Colorado avoids a Senate vacancy and he is expected to continue serving out his term. Weiser is now the early general-election favorite in a state where Democrats have continued to perform well statewide, although the Republican gubernatorial primary remained close after Election Day, with Victor Marx narrowly leading Barb Kirkmeyer in early July. 

Sen. John Hickenlooper defeated progressive challenger Julie Gonzales, preserving a more pragmatic Democratic lane in the Senate race. At the same time, Melat Kiros defeated longtime Rep. Diana DeGette in Denver’s 1st Congressional District, and Manny Rutinel won the Democratic primary in the competitive 8th District, where he will face Republican Rep. Gabe Evans. Rep. Diane DeGette currently serves in the House Energy and Commerce Committee, which has jurisdiction over health care issues.  

Maine became an important Senate-watch state as well. Graham Platner, the Democratic Senate nominee, suspended his campaign on July 9th after sexual assault allegations; Maine Democrats are now preparing for a process to select a replacement by the end of the month. The disruption matters because Maine had been viewed as one of Democrats’ core pickup opportunities against Sen. Susan Collins. 

Within the AHPA footprint, the next major primary dates are now clustered in August. Kansas and Missouri vote on August 4th, with Kansas featuring an open governor’s race and Missouri’s ballot including both state/local measures and closely watched congressional contests. Washington also votes on August 4th, including the top-two primary in the competitive 3rd District. Hawaii follows on August 8th, Wisconsin on August 11th and Florida on August 18th.  

Several already-set Senate races have also became more expensive and more nationalized. In Texas, Democrat James Talarico reported raising more than $30 million in the second quarter, escalating the race against Ken Paxton. In Ohio, Republican-aligned groups began reserving major ad spending to defend Sen. Jon Husted against Sherrod Brown. A new Supreme Court campaign-finance ruling allowing expanded national-party coordination could also reshape spending in Georgia, North Carolina, Ohio and Texas, where Senate control is likely to drive national investment. 

The 2026 election cycle is now sending clearer governing signals. Colorado suggests voters are rewarding affordability-focused challengers but not rejecting incumbency across the board. Texas, Ohio, Georgia and North Carolina show that Senate races are quickly becoming national spending fights. The August results will test whether anti-establishment messages, cost-of-living pressure and government accountability continue to shape primary electorates.
