Bradley reported Monday that she had raised that much through the end of last year.
Her challenger, Rock County Circuit Judge James Daley, reports raising nearly $74,600. That includes a personal loan of $6,300.
The winner, to be elected on April 7, will serve a 10-year term. Bradley was first elected in 1995 and is considered to be a part of the liberal minority on the officially nonpartisan court.
Daley has generated support from conservatives as he tries to unseat Bradley.
In recent years, outside groups with partisan interests have spent heavily on Supreme Court races, far surpassing spending by the actual candidates.
