Sen. Steve Johnson, R-Fort Collins, has resigned from the General Assembly after being elected to the Larimer County Commission in November.
The resignation, which will go into effect Jan. 6, opens the door for the Larimer County GOP to appoint his replacement.
Among the candidates interested in the appointment are Rep. Kevin Lundberg, R-Berthoud, Loveland businessman Mike Lynch and Windsor financial planner Deborah Moeck.
Johnson was reelected to the Senate in 2006. His replacement will serve until January 2011 unless reelected.
Johnson previously served for six years in the House of Representatives.
The vacancy committee will make the appointment Jan. 10.
