A physician will replace resigning Sen. Chris Romer, D-Denver.
Dr. Irene Aguilar, a champion of a single-payer health care system who has pushed for adoption of a bill creating one in Colorado, was chosen by the Senate district 32 Democratic vacancy committee.
According to the Denver Post, Aguilar beat Rep. Beth McCann, D-Denver, by a wide margin among the party activists who voted.
Romer is leaving office Dec. 31 to seek election as Denver mayor.
Since he was re-elected Nov. 2 to a second four-year Senate term that begins next month, Aguilar can serve until January 2015 before facing the voters.
