Last week in the Colorado Senate a bill was introduced to move the date on which the state's state and local primaries are held from the last week in August to the last week in June. The bill was designed to bring the Centennial state into compliance with the federal mandates called for in the MOVE act passed by Congress in 2009. Sponsored by Senator Rollie Heath (D-18th, Boulder), the State, Veterans and Military Affairs Committee chair, SB 189 also shifts the state precinct caucuses -- used for presidential delegate allocation -- up from the third Tuesday in March to the first Tuesday in March.
As was discussed earlier on FHQ in the context of the Minnesota caucuses situation that arose in February, it is rare for state law to cover the timing of caucuses. Typically that task is left up to the state parties. However, Colorado and Minnesota are the two most consistent exceptions to that rule.
The Colorado bill was introduced on March 10 and referred to Heath's committee then as well.
