Stan Garnett WILL Run For Attorney General Against John Suthers

Boulder County District Attorney Stan Garnett confirmed Wednesday that he will challenge Colorado Attorney General John Suthers in 2010.

Garnett confirmed weeks ago that he was mulling a run in response to a lawsuit filed by Suthers claiming the federal health care reform legislation passed in March was unconstitutional. At the time, Garnett called Suthers' lawsuit, which has been filed in conjunction with over a dozen GOP attorneys general from other states, "a mistake and a misuse of the office of attorney general."

Garnett told the Denver Post today that disagreements with Suthers's policies drew him into the race. "John is a very honorable guy. He has been helpful to me in the way that the attorney general should help with local law enforcement issues, but we have principle disagreements."

Garnett's stance on medical marijuana is likewise in conflict with Suthers's. The Boulder DA, who once said he wanted to be "the most progressive district attorney in the state on the issue of medical marijuana," told the Post he's "tried to take a position on medical marijuana that focuses on local control of dispensaries, and managing dispensaries in a way that is consistent with Amendment 20."

Suthers has been critical of the dispensary system, arguing that it does not follow from the language of the Amendment 20, which became law in 2000.

Garnett told the Boulder Daily Camera he is planning a press conference and will have his paperwork filed by Thursday.
