From THINK PROGRESS:
Last week, former Rep. Tom Tancredo (R-CO) gave Colorado Republican gubernatorial candidates Scott McInnis and Dan Maes an ultimatum: drop out of the race and make room for him under the Republican Party ticket, or face his third party candidacy. It turns out Tancredo is following through on his threat. The Denver Post broke the news earlier today that Tancredo will seek the nomination of the Constitution Party once he files some papers and registers as a member. However, Tancredo is running into some heavy opposition from his own right-wing base.
