Tancredo is now the official candidate of the American Conservative Party of CO, for governor:

Today is a great day for the people of Colorado as we, the American Constitution Party, Colorado’s affiliate of the Constitution Party, the nation’s largest third party, welcome a good friend and great conservative to our ranks. Congressman Tom Tancredo has found a home in our organization and joins with the likes of other political luminaries whose parties have abandoned the principles on which this great nation was founded. In the American Constitution Party, Congressman Tancredo has a base from which to provide support for his American ethic and the encouragement to bring those ideals to the political arena. He gives to Colorado voters a real choice to return to the founding principles that allowed our nation to become the greatest engine for freedom and prosperity the world has ever seen. We are pleased to have Tom Tancredo run for the office of governor on our ticket.

They are the affiliate to the Constitution Party, home of hard theocratic right-wingers.
