Four Democrats now will be facing off in the June 3 party primary for the District 1 seat on the Linn County Board of Supervisors.
The latest addition to the race is Andrea Jackson, 45, a teacher at Regis Middle School in Cedar Rapids.
A candidate must secure 35 percent of a partyís primary vote or the decision falls to the partyís county convention.
In a statement, Jackson said she has decided to seek the supervisor post because she believes her professional experience will let her be a strong advocate for families and children at a time of change and "uncertainty" for human service agencies and groups.
She also said it is important to make good decisions to develop and preserve the countyís natural resources with both flood protection and recreation in mind.
Jackson, of 1357 O Ave. NE, has taught at Regis Middle School for 13 years and has worked in education for a total of 18 years in Linn County.
She has a bachelorís degree in education from St. Maryís University, Winona, Minn., and a masterís degree from Viterbo College, La Crosse, Wis. She is the mother of three children.
Jackson is joined in the District 1 supervisor race by Ian Cullis, 65, who chose not to seek re-election as mayor of Robins to run for supervisor; Jim Houser, 59, who served as Linn County supervisor for 19 years before being defeated in 2010 in a close race with current supervisor, John Harris; and Kim Taylor, 45, a veteran staff member in Cedar Rapids for Sen. Tom Harkin.
District 1 Supervisor Lu Barron, a Democrat, has decided not to seek re-election. This is her eighteenth year in office.
