The Colorado recall election of 2013 was a successful effort to recall two Democratic members of the Colorado Senate following their support of new gun control legislation. Initially four politicians were targeted, but sufficient signatures could only be obtained for State Senate President John Morse and State Senator Angela Giron.
During the petition drive, national organizations on both the gun rights and gun control sides became involved by providing mailings and donations. Once the petitions were submitted, Morse and Giron challenged the effort in court, but were denied the injunction that they had requested from the court. A further court hearing resulted in the election being conducted in-person rather than by mail, which also led to Giron complaining of voter suppression.
In the election, held on September 10, 2013, both Morse and Giron were recalled by the voters of their districts and replaced with Republicans George Rivera and Bernie Herpin, respectively. It was the first time a state legislator in Colorado had been recalled. In the 2014 Senate elections 13 months later, both Rivera and Herpin were defeated by their Democratic opponents.
In early 2013, the Colorado legislature passed a series of gun control bills following the theater shooting in Aurora, Colorado and the Sandy Hook school shooting in Newtown, Connecticut. The new laws provided for a ban on magazines holding more than fifteen rounds of ammunition, a universal background check, and a requirement that buyers pay a fee for the background check.
The initial recall petitions targeted Senate President John Morse and State Representative Mike McLachlan. Two additional petitions were also filed against Senators Evie Hudak and Angela Giron. All four are members of the Colorado Democratic Party.
