[3] The ACN qualified for major party status in Colorado after receiving more than 36% of the vote in the 2010 gubernatorial election.

[9] Former Republican Congressman Tom Tancredo ran as the party's candidate for Colorado governor in 2010 after the campaign of Republican Party nominee Dan Maes collapsed politically.

However, because of the additional organizational, financial, and compliance requirements triggered by major party status, ACN leaders were ambivalent about the change.

[27] In the 2022 elections, the party fielded candidates in races for US House, in Districts 2, 4 and 5, as well as in statewide elections for Governor, Lieutenant Governor, Secretary of State, and in District 8 for the Board of Education.
