Tancredo, in a radio appearance today, said he was trying to do "my level best to do what’s necessary for the conservatives in this state" by entering the race.

As our colleague Kathy Kiely noted last week, the Republican establishment disagrees with Tancredo’s move. Colorado Republican Party Chairman Dick Wadhams has warned that Tancredo’s bid will throw the governorship to Denver Mayor John Hickenlooper, the Democrat who is running unopposed for his party’s nomination.

Trancredo had warned the two Republican contenders, Scott McInnis and Dan Maes, that he would enter the contest if they refused to end their campaigns after the primary if polls showed the winner falling behind Hickenlooper.

According to The Denver Post, Wadhams and Tancredo had an "all-out brawl" on a Colorado radio station this morning and called one another liars. On Sunday, the leaders of nearly two dozen Tea Party groups also asked Tancredo to refrain from entering the race.

In a letter, they urged Tancredo to "stay in the Republican Party, let the process play out for the governor’s race ... In other words, to trust and respect the newly awakened, energized and informed voters of Colorado."
