MADISON, Wis. (AP) -- The three candidates for Wisconsin Supreme Court have one more day of campaigning before Tuesday's primary narrows the field.

The top two vote-getters in the primary will advance to face one another in the April 2 general election.

Incumbent Justice Pat Roggensack is seeking a second 10-year term on the bench. She is being challenged by Marquette University law professor Ed Fallone and Milwaukee consumer law attorney Vince Megna.

Roggensack is the only one of the three candidates who has had enough money to advertise on television in advance of the primary. A conservative outside group, Wisconsin Club for Growth, has also been running ads backing Roggensack.

Megna and Fallone argue that the current makeup of the Supreme Court is dysfunctional and Roggensack needs to be replaced because of it.
