In an article in the Denver Post http://www.denverpost.com/commented/ci_23486124?source=commented-news it has been reported that the Colorado Secretary of State has certified the petitions to recall State Sen John Morse. According to that article there were substantially more than enough valid signatures on the petition.
Morse is the current State Senate President and was a primary mover in getting Colorado’s new highly restrictive, anti Second Amendment laws through the legislature. In a separate action a lawsuit has been filed by many sheriffs in Colorado to have the new state laws nullified as being unconstitutional with regards to the US Constitution.
A claim has been made that the petitions may not have contained the proper wording. More on this as it becomes available. Please read the article linked above to obtain more specific info.
