From a constitutional perspective, the Lieutenant Governor of Colorado is one the weakest second-ranking state executives in the nation. This is because the Colorado Constitution sets aside no specific duties for the office.
The office is acknowledged in Article I as being part of the executive branch of the State of Colorado, but that is it. Until the mid-1970’s, Colorado’s Lieutenant Governor also served in a legislative capacity, as President of the State Senate. So, currently, their power and duties are dependent upon the willingness of the Governor and the Legislature to grant them to the office.
