The Democratic Party is facing a challenging primary campaign in Colorado, with multiple allegations of favoritism and criticism of the governor. The tension reflects internal frustrations within the party as pressure grows to win in November's crucial midterm election, but could potentially alienate unaffiliated voters who already see both major parties as too extreme. Most cases involve establishment Democrats against new candidates aligned with the party's left wing. This aggressive approach reflects the first wide-open race for Colorado's top executive offices in eight years, with incumbents all term-limited. The Democratic Party in Colorado is expected to sweep the governor, attorney general, secretary of state and state treasurer races, while it is also predicted to have more than 1 million registered voters.
