A group that tracks spending in judicial races said Tuesday that outside groups combined to spend more than $3.5 million on TV ads in Wisconsin. That tops the previous record of $3.4 million in the state’s 2008 race.
The 2011 figure includes all spending through Monday. It’s expected to rise further when Tuesday’s numbers are included.
The biggest single spender was the liberal Greater Wisconsin Committee, which spent about $1.4 million.
Its spending was eclipsed by three conservatives groups that combined to spend almost $2.2 million.
The race is between incumbent Justice David Prosser and Assistant Attorney General JoAnne Kloppenburg.
It’s drawn national attention as a possible referendum on the state’s polarizing union-rights law.
