Less than 10 percent turnout is being predicted for Tuesday's primary election in which the field of candidates for the state Supreme Court will be reduced by one.
The Wisconsin Government Accountability Board issued the prediction Wednesday.
The Supreme Court race is the only statewide contest on the ballot. Incumbent Justice Pat Roggensack faces Marquette University law professor Ed Fallone and Milwaukee attorney Vince Megna.
The two highest vote-getters will advance to the April 2 general election.
Turnout for the past three spring primaries for Supreme Court races have all been under 10 percent. In 2003 it was 6.8 percent, in 2007 it was 6.7 percent and in 2011 it was 9.6 percent.
GAB director Kevin Kennedy says he expects turnout this year to be in that range.
